Nice game! I included it in my compilation video series of all of the GBJam 5 games, if you'd like to take a look :)

The graphics and music are both great and the gameplay is solid!

I feel the windup for the charge attack is a bit too long sometimes. Maybe you can vary the length of windup depending on the charge level. Adding windup animations will help immensely for visual feedback; it reassures the player that their inputs are being acknowledged.

Overall, I think this is one of the better games I've played in this jam.

It has some good mechanics and some nice music but it feels like it needs some more polish and animations. In particular I'd suggest either adding some frames before the charged attack of the wolf preparing to swing or remove the delay from the charge. I'd also suggest having the camera pan towards the exit before showing it open, as jumping straight to the exit looked a bit jarring and left me unsure of where it was.
