Really fun idea! Kinda reminds me of a game my friend and I made long ago called PLACEHOLDER NAME, where you played through a platformer and had to deal with various bugs/missing features 😂
I really like the concept and I definitely think there's so much that could be done with it! I also think it's one of the best modifier uses I've seen so far this jam!
Aside from that, it's just a very polished-feeling platformer. I liked the tight controls and the general aesthetic.
Overall really cool! Thanks for submitting!
