A few things I've noticed while playing:
- Triple mask form doesn't destroy boxes above Crash, most levels it's fine but in Snow Way Back there's a couple of 5 bounce boxes that cannot be body slammed if the bottom box is destroyed
- last TNT was blown up when leaving Hang 'Em Back's bonus, with the box counter showing 24/25. Still got the gem, just a UI bug.
Otherwise love this fangame, really does play like a proper Crash game <3
