Oh this was adorable! I wish I could make these but my brain is screwy. (I'm autistic... they say. O.o)
I love these so much. every time I go to try and make one, something doesn't pan out. the program I found that I could use is probably going to stop being made, and well... argh. I have a hard hard time understanding what I read or hear. something gets messed up in my head and I can't understand. But this is so cute! the algebra was beyond me though; didn't even realize it was algebra- that's how obscure it was for me. a bit too obscure for the rest of the game I think. BUT if you made it a non math puzzle and KEPT that sense of surprise obscurity, I think that could be a good gimmick/signature for a series, like Coconuts Park, Tesshi-e, Detarou, Robamimi, etc. the cat, and the three balls idea, too. it's adorable!
