This is a neat idea for a puzzle game! I like how it fit the theme At first I really liked the sound for landing on the gold, but after a while I started to get tired of it (maybe because I kept losing on the last level. I felt like your wall jump was too unforgiving. There was no "lock on" to the wall at all, and so if you weren't holding toward the wall when you jump, it would just fall, even if you had already made contact. The other thing that would have helped was some kind of visual indicator that you were touching the wall (like changing the sprite to a wall slide frame or adding slide particles). I really wanted to beat the last level, but I just couldn't get all the precise jumps (50+ tries :tears:). It's possible that with a few more levels in between the difficulty ramp wouldn't be too much. Overall nice work!
