Nice play with the theme, also very good ai lmao, I've been getting ties for 10 minutes now
This type of game doesn't work well with physics. I keep getting over walls and just getting flung in the sky by noting. Also it's a really blank game, not textures or some nice effects. Sorry if this is a bit harsh but I'm telling my honest opinion.
I love the concept and the style of this. Also the animations are good.
My only problem with it is that I can't see some of the enemies and I kept getting killed cuz of that. Maybe you can add like a warning effect on the screen when a bullet is appearing offscreen.
I wold play this if it was a big game tbh.
The idea is good, and I see how it connects with the theme.
