Thank you so much for the detailed feedback.
Yes the checkpoints were fake on purpose. Checkpoints were somewhat provided through level design though.
That being said, we never intended players to have to rely on a Reset, except for the one pitfall near the very bottom.
I'm sorry you experienced the clipping issue that forced you to reset. That's on me and I totally understand the frustration. It didn't occur to us in testing, but that's no excuse.
Thanks for taking the time to play and to give such valuable feedback. ♥️♥️
