It's pretty fun to play ! and graphics have a cool vibe, I like it !
The dash is cool to use, but once in a while it goes way further than usual, which catched me off guard and got me killed a couple of times. But that's a bug, no big deal for a jam game :)
The only thing I think the game is lacking to make it really fun to play is some kind of way to tell when an enemy is about to shoot. It would make the game easier, so the balance would maybe need to be adapted, but it would give a lot of useful information for the player to make decisions.
