Run into a bug, where the cutscene of meeting Betty in "Path of Righteous Light" would trigger far away from the actual location.
The ellipsoid barriers you, enemies and your skeletons sometimes get are positioned a bit too far up relative to the upright character model.
When facing a wall and using the Crushing Teddy skill you can get sucked through the wall and fall eternally.
Another (minor) issue: When using the Crushing Teddy in the homebase, the lovely slime girl Gucha might get stuck halfway in the floor^^"
In some (rare) cases the camera would zoom in and then get stuck in the zoomed position.
Still got some optional levels to beat, but it was mostly fun so far, despite some frustrating deaths every now and then XD
