It could use a background, since at the start I wasn't sure if I was moving or not. The black monsters have the same speed as you, so you can't escape them, nor shoot them. Funny ending.

That black bug :(
The colour palette is cheerful - a nice background would have helped.

I wasn't sure what I was supposed to be doing, or even if what I was doing was actually having an effect on the game. Some more info would have been good, or a background to let me know I'm moving. I feel like there's a good start here, now just polish it off and you'll have a playable game.

Needs a background, like others have already said. I found it really hard to hit the enemy bugs too, especially when they were up close. Maybe make them move slightly slower, so you have more time to target them?

Hah, I enjoyed the post-game over screen!

I'm also going to chime in and say a background would greatly help feel like you're moving through an area (Although to get that exact effect, you may have to do something like parallax scrolling. Huzzah for feature creep!)

Otherwise, good effort. That Black Bug and I are not friends. He is not getting a Christmas card from me. :(

I can't seem to play the game. When I hit a small yellow ball, the game freezes and I get these exceptions in the console :

The inability to choose where to shoot, and not being able to shoot means that the game is too hard. So I wish I knew what happened after getting enough food to evolve. Also, I agree, needs a background (or a movement animation?). Funny ending!

Pressed Play and game just sat there. Dunno what the problem is.

It was frustrating to not have the firing on an independent axis. A scrolling background would help a lot too.
