What fun idea! 
Merging a clicker with a platformer isn't something I've seen before! It offers a nice little break from the monotony that clicking games usually bring. I like that even the main menu is technically a purchase lol. It's a funny and literal take on the theme. One thing that stuck out in the first level or two when I didn't have as much money was getting stuck and losing the resources I built up for it. It would be nice if you could get a preview of the level beforehand. Additionally, the balance on the last levels was trivialized by the fact you can grind up all the resources beforehand. So maybe new options are unlocked as you go? Alternatively, I could see a branching world map being really cool for this.
Anyway, I like the idea a lot, and with balancing it can be even better. Good job finishing!
