Thanks for the feedback, I had a lot of fun design the sfx on this one. As for your mystery mechanic I believe you are describing the infamous "light button" a real last second add that broke a lot of stuff. The blue buttons are light and they have to be slimed in-order for the level to be completed. (they are also needlessly confusing and break the 5 level, if I had a time machine I would loop back in time an slap dev me for adding them)
