I'm not sure if I understood the game correctly or what. But it seemed like your statistics don't really affect anything, and at least upgrading your attack speed doesn't seem to register. But it does eat your chips as payment. I also tried buying weapons but the game only took the chip amount set, not the amount of weapons set as I was expecting.
Alas, my experience was just playing tag with the enemies.
I would've also sped up the intro cutscene. When playing and rating jam games you do want to get into the action fairly quick.
Graphically the game looked nice.
Good work.
