firstly, SUPER THANK YOU! Im glad you thought this was original and impressive! it really makes all this time worth it!
as for the button issues, I 100% can say that's my bad, I may've accidentally in my rushing to finish everything (since my main focus was mechanics and artwork with music on the side haha) forgot to properly fix that! (the pause menu mainly is a mess somehow o.o)
basically I made some oopsies and forgot to tell the game what it should do with those buttons o.o
I do plan on fixing it the second I can! but I do truly thank you for bringing it up! ^^
