I think that if you made that a game, you should have one endless level. But that's my all-time favorite animated 4 color piece. Favorited.

You may use Motorola MPX-200 external B/W screen for this, sure =)

There are solid shadows with deep gray color. Try to play with shadows, making 'em flatter or deeper depending on a distance. May help =)
Hahaha I love the pitch "lots of explosions" looks like it could be a real game for... a digital watch?
This reminds me of stuff I'd play on my phone. Ahh, those were the days, hehe...
Well done!
