Thanks! Yeah, the collisions have been wreaking some havoc. I know about the player/enemy one, which I had trouble figuring out before I submitted. The button one is currently a bit of a mystery, though. Haven't been able to replicate it and I've tested on a few different browsers and systems. Wondering if resolution is somehow affecting it? If you are able to capture a vid/gif of it happening, that would help loads!
Thanks for playing, and glad you found it thrilling!
