this is really fun, we like it a lot! a few criticisms (which i imagine could be fixed for a postjam version) though:
- having no fullscreen or screen resize is annoying
- the lack of a save mechanic is particularly frustrating
- the ability to go back a level had us accidentally having to redo puzzles multiple times
- the little knockback you get from a failed grapple can sometimes allow you to phase through a wall (if you then go towards the wall immediately after being knocked back right against it)
aside from that, good stuff!
