I stopped after I finally got a decent run (current enemy modifiers were 3 2 6 2), had the most success with homing bullets although I also picked and upgraded the minigum before taking extra health.
The game is fun. I like this kind of controls, the different guns make a real difference and the difficulty is on point for the jam with the appropriate sequence lengths and things happening on the screen in the same time and cool bullet patterns to dodge.
Some sound effects would surely improve the game.
Thanks for sharing!
