I landed on the spider at the top of the first spring platform right at the edge of the cliff and the game froze with my character crouching on top of the spider which continued it's walk animation while staying in one place at the edge. There is no way to quit the stag or reset. I have to refresh the entire page because of this bug.
Several other times I fell right through the ground, and I also ran right through the first cliff into the terrain and was hit by a spider inside there.
Buggy mess, not even playable.
