Eh... Not bad?

Honestly could use a lot more.

>Only one enemy type until you get to the boss, which seemingly takes forever. While graphics aren't necessarily BAD, there are very FEW of them.

>The sound when enemies appear/shoot at you is OBNOXIOUSLY loud, hurts my ears even when my speaker volume is at 30%. Glad there's a mute button, would recommend sliders for volume control.

>Speaking of buttons, would be nice to have a Pause button.

>The first boss seems to shoot so much it LAGS the game, unless it's just my browser.

>The game is too large to fit on the screen. Definitely recommend resizing this.

>Maybe checkpoints? Although, the game seemed pretty easy until the point where you get to the boss.

>Hitboxes are very tiny or random? It seemed like 90% of every shot just phased right through me, unless it was actually doing damage and there's just no health bar.

>Not really required for a "hentai" game, I suppose, but maybe a bit of story just to tell the player what's going on? (I really wouldn't classify this as hentai, honestly. You don't get to see much except for the Game Over screen.

I suppose not a BAD attempt at a bullet hell, but it still could use some work. There's a BIT of potential in there, unless you want to make it explode and function insanely like an actual game, but that would require much more effort.

(...Also, why naked fairies...? What gave you that idea? FAIRIES? Well, at least it's not MLP...)
