I think having the wall sliding and jumping made this way harder than it needed to be. This is more of a platformer where you need to complete the level perfectly, rather than a puzzle game, as the wall jumping adds a large timing element in that requires skills. I think actually showing the level before the player plays it through is a good idea, as well as indicators for the remaining jumps and dashes. I got stuck on level 3 for a long time, as I didn't see any reason to use dash initially, but I like the puzzle of saving jumps using strategic dashes. Unfortunately there isn't much puzzle aside from that, as the money makes it pretty clear what you need to buy, and the rest is up to the player. Really cool interpretation of the theme "everything has a cost", and I hope you continue making games!
