Stunning entry
I played it a bit on first day but wanted to wait till I had time to play and complete before rating or commenting...
The graphics are charming, with lovely animation. The hook mechanic really well implemented, a couple of minor points I got stuck on - but given the complexity of the mechanic it worked brilliantly for a game jam.
Found the levels occasionally verged on the frustrating, (but the fact I kept compulsively coming back to finish them, and get my revenge on that darn Bear) shows it managed for me to stay on the right side ;)
If there is any slight criticism as an MVM entry it felt a little more like a leveled platformer than a metroidvania (especially once you started to get to the difficult navigation parts), but that is no detraction on the quality of the game.
