I thought that the idea of having the two colors that you're swapping between was a fun idea. It makes it so the player has to decide what color they want to risk empowering before starting a round. Like I personally spammed one color early on so that harder content early on would have less power on the color I didn't choose, but I could also see why a player might want to simply switch off between rounds for a gradual rise in difficulty. This kind of design where you have to make decisions based off of risk and resources is what really drives player engagement. Keep up your smart design sensibilities!

I can definitely see the beginnings of a neat game here, but I'm guessing you ran out of time to do all that you wanted with it. My only real complaints are that I couldn't see my health remaining and that the music stopped playing after a short while. Aside from that it just needed a bit more content, I think.

I do like the concept of having two sides, and which you pick changes what empowerment they each get. I assume the enemy power-ups were cumulative (or meant to be), but it was hard to tell because if you just spammed attack speed and damage they couldn't really do much lol
