Yeah the wave logic is based on enemy death but sometimes its been registering a single kill as multiple but usually very rarely which can cause the problem you ran into. I'm not sure how bug fixing works for the jam but I would definitely be down to go back in and give it some TLC! I'm glad you caught the reference for the junk boss though!!! xD The game gave me a sort of ATHF vibe so I thought it would be a cute thing to add x) I wanted to get a health bar that hovers over the junk shop as well, if we are able to go back and work further on our games either after the jam or even now I would love to do so!! This being my first jam and second game ever I'm still very new to it all. Thank you so much for the feedback and assistance though, I greatly appreciate you checking it out!!!
