Ha, oh yeah, that guy is super chonky. When Kai came up with the design for him, we loved him immediately! And believe it or not, we had 2-3 more potential obstacles already created and ready to go: we just couldn't find space for them in the game's design when it came down to the end of the jam time.
Regarding the platforms, I agree - the platforms were part of the main environment rather than separate objects, and I don't know why I didn't think to separate them like that. I wish I'd thought of it, would have made moving platforms and moving barriers much easier.
Thanks for the comment! And regarding the minimap, we did consider that as well, but ended up cutting it as a little bit too much for a jam; we did some testing for the levels, but probably not as much as we should have. Ultimately, Kai is a really good designer and we all have some good experiences with platformers, so were able to supply enough feedback regarding the levels for him to be able to build it cleanly. It worked extremely well.
