Very fun game! I really liked the art style. The purple upgrade (projectiles fires 2 or 3 times more) feels a bit OP (maybe that's another integration of the theme?), but not to my displeasure. Great work! :)
Thanks! The projectiles overall are too strong, or all the rest is not strong enough! We went with more upgrades rather than less with balance. I don't know if it was the right call. Glad you enjoyed it!
