You probably want more apps, but more than that, you want the right ones. That;s what we're here to deliver with the weekly Google Play App Roundup. This is where you'll find the best new and newly updated apps and games on Android. Just click the link to head right to Google Play.

The Play Store has a number of popular podcast apps, but it's been a while since a new contender has emerged, but Audvel is promising despite its newness. It might not have as many features as the more mature alternatives, but it's free. That counts for something.

One of the cool things about Audvel is that you don't have to set up a separate account—it supports Google account logins, but a standard email account login is available too. After logging in, your subscription data will be synced to new devices upon setting up the app. After opening the app for the first time, Audvel offers up some suggested podcasts in categories like tech, science, and business. I think the top picks are pretty universally liked, but there aren't many in each group. A few more suggestions would be nice.

Once you've got some subscriptions, you can view them all on a single page with big thumbnail icons. Each podcast has a details page that lists recent episodes, a description, and controls to unsubscribe and refresh. I like that the page is themed to match the podcast's thumbnail as well. You can tap on an episode to stream it, or hit the arrow to download it. There are also settings in the app to have new episodes downloaded automatically. Unfortunately, you can't import a podcast list from other apps, but you can add custom feed URLs.

While some of the advanced features from other apps are missing (importing, Android Auto, themes, etc.), you do have built-in support for multiple playback speeds. You can increase to 1.2, 1.5, or 2.0x speed. The app correctly downshifts the pitch to compensate for the higher speed as well. There are also persistent playback controls at the bottom of the app while you've got an episode going.

Audvel still has a way to go before it's the match of something like Pocket Casts, but it's already impressive. When you consider it's also free, that's even better.

I will admit to being skeptical of ZOMBIE AnnihilatoR when I first came upon it. I mean, look at it. It' far from a perfect game, but I do find myself compelled to play it. For one, shooting zombies is a good time, but ZOMBIE AnnihilatoR also does an admirable job of creating a tense game with a very simple stationary shooter approach.

Your goal in ZOMBIE AnnihilatoR is (obviously) to annihilate zombies. How you go about that is the fun part. At your disposal are a number of firearms, most of which are locked when you start playing. Each "day" in the game sees your character stuck in place while a horde of the undead mill about nearby. Each day comes with a specific task, like kill X zombies, get X headshots, and so on.

The controls are typical for mobile shooters, but the lack of walking makes it much more manageable. Just drag to aim and tap the weapon of your choice to fire. You'll never be completely comfortable with dual-stick movement while shooting in a mobile FPS, but this works fine. Some zombies will keep their distance, but others will rush you. So, you have to prioritize your targets. The power ups that are dropped regularly keep the game lively and can turn the tide of battle. They might freeze zombies, make them float, or just reload your weapon instantly.

You will also encounter a myriad of zombies as you progress, some with special abilities. There are also boss zombies that might take some time to defeat. The design of the game is interesting—all the zombies are really animated and over-the-top with exaggerated features and proportions. It's kind of a silly game, but in a good way.

ZOMBIE AnnihilatoR is a free-to-play game, which is at least going to give lots of people a chance to try it. You get in-game currency for completing levels, but thankfully there's only the one currency. You spend it on new weapons and power ups before tackling a new day. There are ads that appear in the menu and after every few levels. They're annoying, but there's a $2.99 in-app purchase to get rid of them. ZOMBIE AnnihilatoR is at least worth checking out. You might find it worth buying.

Topsoil is a relaxing game about farming. Well, not really. It's a puzzle game that uses farming and gardening as its metaphor. The land changes each time you harvest a plant, so you must keep everything as consistent as possible to harvest more plants in a single go. The longer you can harvest, the more points you get. And points are important, right?

The top layer of soil, in which you will plant your seeds, cycles between blue, yellow, and green. Each time you harvest something, the soil advances to the next color. You can tell which one is next from the front edge, which is visible as a cut-away. You need to keep the colors contiguous if possible because of how harvesting works.

Each turn consists of three seeds and a trowel (which indicates harvesting) that slide across the top so you can see what's coming up next. Most seeds are harvestable right away. Simply tap a plant, and any matching plants in adjacent squares will be removed as well. However, this only counts within the same color soil. That's why you need to avoid splitting the game board up into too many blocks.

Additionally, some seeds take a few turns to fully grow. These include flowers and trees. The regular crop plants are the ones that are instantly available. The multi-turn seeds need to be carefully positioned so they don't interfere with your next few turns. Specifically, you need to make sure you can clear at least three spaces per turn. If not, you won't have enough spaces for all the seeds, and it's game over.

Topsoil has a very simple look with gentle pastel colors and clean black icons for your plants. The animations are also very slick.

Topsoil is free, and there are no ads. However, you only get five rounds per day in the free version. You can get more plays by watching an ad, or you can buy the full version for $3.99 via an in-app purchase. That seems a little steep compared to the competition, but it's a good game.
