Amazing game too !
I especially love the graphics. The handraw artworks that are animated in a few frames brings so much. It could really be the art for a finished and polish game. The bullet patterns are so cool to play with, the upgrades are so satisfying especially if you manage to stack them.
I spent so much time trying to beat the game on hard mode but I'm not good enough lol, I gave and beat it in normal mode on the first try after that. I think that I'll come back later to try to beat it in hard.
Probably my favorite submission, and surely the game I spent the most time on. Insane job !
Also, if you press WASD key + arrow key at the same time you double your speed, it's a fun mechanic
