It's a cool idea to combine platformers and incrementals but the balancing is sorta whack. I spent the first ~10 runs doing the same thing over and over again and only buying money multiplier upgrades and a few time extenders so when I could actually afford a movement upgrade I immediately broke the game in half and got 10,000 coins in one run, and just dumped them all into more money multipliers to break the game even faster
The platformer controller also feels very slippery and heavy, which I think is because the walk animation isn't synced up to the player movement and there's no coyote time.
Still I think this has a lot of potential and I did have fun with the movement mechanics, so expanding on the game is a good idea and I wish you luck making it.
