A new week has dawned, and with it comes a new list of great things happening on Android. This is the Google Play App Roundup where we tell you what needs to be on your phone or tablet right now. Just click the links to head to Google Play and grab these apps for yourself.

Weather apps with a lot of data tend to be not very attractive, and apps with attractive design tend to be lacking in data. Weather Wiz seems like a good compromise between pretty and functional. It's also completely free, at least for now.

Weather Wiz reminds me a little of the weather app HTC builds into its phone, but it has a lot more data and features than that app. In the main view, there's a temperature readout at the top along with some notes on the current conditions. At the bottom is an hourly forecast that can be scrolled through to see what's coming up in the future. I really appreciate having this data so easily accessible in the app.

The animated background image on the main screen is controlled by the theme you've chosen. It will, of course, change based on the current conditions. This is where you'll encounter the upsell—some of these themes cost $0.99. There are about 12 themes right now, and five appear to be paid. They don't seem any better than the free ones, though. I'm particularly into the Material theme (right) and the space theme.

If you scroll down from the main screen, you'll find all the other data in Weather Wiz. Oddly, you have to scroll from the bottom section with the temperature timeline. Swiping on the background doesn't work, which seems awkward and wrong. At any rate, the background is blurred as the new weather readings slide into view. You get more details about current conditions at the top, then as you scroll down there's a rundown of weather for tomorrow. Below that is a 10-day forecast. At the very bottom is a cool sunrise/sunset graphic.

Weather radar is accessible from the navigation menu, and it'll get the job done. It is very pretty with animated wind patterns, but there's no true animations for radar changes over time. The accuracy of the precipitation (the most important radar use case, I think) seems lacking. This data comes from a third-party, so this isn't necessarily the developer's fault.

Lastly, there's a full suite of widgets for Weather Wiz that are mostly very good. There are several different sizes, and each theme has its own backgrounds for them. However, you can also use the more generic stock ones if you like. There's an add that pops up when you add a widget, but after you've cleared it, you won't see it again until you add another Weather Wiz widget. Overall, I think this is a great weather app with a not too annoying monetization setup.

I went into Towaga expecting a fairly typical 2D shooter, but I came away impressed with how strategic it is. Even without adding any complicated new elements to the basic premise of "shoot everything that comes at you," Towaga manages to be a unique gaming experience on Android.

The gist is that you must complete "The Black Moon Ritual." What does that mean? Apparently it involves exorcising a lot of demons, which will rush toward you as you stand atop a series of temples. You can destroy them by directing a beam of light in their direction, but the mechanics are a bit deeper than that.

The thumbstick is in the lower right corner, but there's also a left-handed mode. Simply point in the direction of the demons, and you'll see a ring of glowing runes fill up around them. When it's full, they are ready to be exorcised (this also stuns them). You can think of this like a life bar for the demon, so the more powerful ones have to be blasted for longer to make them ready for destruction. You can have multiple monsters stacked up ready for exorcising, but they aren't exorcised until you stop firing. Then all defeated foes are cleared and you get a health boost. The key is finding the right moment to do that. Wait too long and the stunned creatures will still be able to attack; don't wait long enough and you waste valuable time.

In addition to your standard attack, there's a more powerful version that's triggered by pressing the side of the screen opposite your thumbstick while attacking. This produces a wide beam of light that can hit many enemies and deal a lot more damage. However, it also drains your life. Don't be too afraid to use it, though. You take a lot of damage being hit, and exorcised monsters heal you a little. It can be worth it to lose a little health in order to light up a cluster of enemies.

The visuals in Towaga are fantastic. The background has a cool hand-drawn look and the animations are very smooth. There's even a 60fps mode that makes the game absolutely buttery. It does consumer more power, though. I can feel my device heating up more when I play with 60fps enabled. I think it's worth it, though. The lighting effects look fantastic, too.

Towaga will cost you $2.99 for five worlds. Each of them is pretty challenging—I've only managed to get through two of them. There's also a second mode that's unlocked when you beat the game.

The Dynasty Warriors games have long been hack-and-slash in its purest form. There's a story, sort of, but no one really pays attention to that. All that matters is swinging giant swords and taking out dozens and dozens of enemy troops in mere moments. Now you can get that experience on Android with Dynasty Warriors: Unleashed. It's been in beta testing, but that's set to end today. It's very much like the console games, but you will (sadly) have to deal with some in-app purchases.

There are several different ways to play Dynasty Warriors: Unleashed, but honestly they all have a lot in common. Playing Dynasty Warriors is as much about the cool visuals as it is about actually controlling the game. You can have up to three officers in your squad at any time, each with different attacks and elemental abilities. It's important to look for the color coded icons above the enemy officers to see which element they are aligned with. Choosing the appropriate officer as your avatar at that time can boost your attack damage. Likewise, if you have the wrong element selected, your attack damage is reduced.

The controls are about what you'd expect—a thumbstick on the left and attack buttons on the rights. Your main attack can be held down for continuous attacks. Just make sure you're pointed in the right direction. The buttons around it are all your special attacks, which take time to recharge after use. You should save those for groups of enemies and officers.

There are over 80 different officers in the game that can be recruited to your team, and they can all be leveled up and given better equipment. The equipment management and modification system is really where all the strategy is in Dynasty Warriors: Unleashed. Your ability to complete a stage is almost entirely based on how much raw power your officers have. If you aren't adding and upgrading your items as you find them, you'll find yourself overwhelmed.

As I mentioned above, the visuals are half the reason for playing this game. The frame rates are good, even with a ton of troops swarming around you. Each special attack has a huge, over-the-top animation and lots of lighting effects. The music is somewhat cheesy generic guitar rock, but that's in keeping with what we've come to expect from Dynasty Warriors.

This is a free-to-play game, so that means you'll have some in-app purchases floating around. There is an energy system, which burns off five points out of 100 when you play a level. One point comes back every few minutes. So, you could probably play for an hour or two before you ran out of juice. After that, in-game currency is used for instant recharges. You can earn some of it from playing and logging in every day, but buying it with cash is also an option. Likewise, you can recruit officers for free using the currency you earn from playing, but you can get more of them with better stats if you spend some money.

I've seen worse IAP system, but it's not the best, either. But hey, Dynasty Warriors is still some good, mindless hack-and-slash fun.
