Everything about this game is great except the fact that the gameplay can get frustrating very fast. It's more of a threading the needle type puzzle game masquerading as a plarformer. My mind is telling me this is a type of game I'm well familiar with, yet minor drops outright kills the character. I think maybe it needs to have more checkpoints (maybe as part of an easy mode) It's a good thing you added a skip level feature for this build.
Also, the heystack should be more obvious, it seems like a part of the background like the windows and the work tools.
Anyways I think I'm coming off as a bit harsh because of how much this title impressed me, you guys absolutly nailed the Gameboy aesthetics, sound (which was fantastic on its own), and the design philosophy. The fact that you actually released a Gameboy build is the cherry on top.
This is really great, bravo!
