Hey i am loving the game! However there has been a couple issues.
1. once i got a 300% speed and 300% acceleration upgrade in the same run, and if i tried to move in any of the levels it would crash the game.
2. sometimes the black hollies spawn directly in the path, so i cannot explore the rest of the level/ or will block off combat or the shop sometimes.
Other than that i just hope you are working on optimization, so i can play for longer!!
i really love your soundtrack, and the art-style here, you have an amazing skill and i cant wait for this to grow larger!
EDIT: i forgot to ask if you could add some min/max-ing perks so that its more awesome. Percentage based upgrades are fine, but you cant really feel the progress you are making with them. Personally, i would swap the loop pool from the shop and the bosses. that way you feel more accomplishment from getting past a level
