This was a lot of fun. Making so many minigames in such a small amount of time is impressive.
I did get an error occasionally, though. Just looking at the stack traceback, it looks like str becomes nil in your text_wave function somehow:
Hmm , I'll have to look into it :/Thank you for playing ! I wish I had time to build more minigames , I was aiming for 10 :'( I was finding it hard with the two button controls ahah !<3
