I think your game is the only one I've seen that makes use of "two colours" as a central gameplay element, so kudos for that. The music and sound effects were also well done. If I could make some changes to the game, I would increase the speed of the player's bullets and add a background texture to better show that they're moving across a room larger than the viewport.

Nice thing, would add some effects on enemy destroy and improve hitboxes. GJ!

Pretty cool game. I found it really hard but it was pretty fun.

Maybe the tutorial instructions can be simplified. The game itself is really fun, I really liked your idea.

COOL!!
I like the color changing thing, very interesting and fun! :D

I like the gameplay a lot, it's clever. It's kind of hard to read the font, and the tutorial is a little confusing. Overall good game!
