Hello, this is a last minute Nesdev Compo 2022 experiment.

Don't expect much polish nor content. There was supposed to be more of a story,  but I'm too tired. Good luck, everyone!!

This game was written in C using the the fantastic llvm-mos.

Amazing mix of puzzle and metroidvania game!

Do you plan any updates?

Probably a bug fix version in the foreseeable future, no major changes /o\

Included Crowborg as part of a NES game compilation (@11:04). Bit of an edited playthrough as I died a few times trying to figure out how the enemies worked. Really not sure if I could avoid that spider towards the end at all.
