ah, I think I understand which part you got stuck on, that was nearing the end, it's a fairly difficult thing to manage, but to get past it, you need to jump, and switch dimensions twice mid air mightve been a bit too hard now thinking.
I play tested to make sure the game was possible. alas this is still a fault on me because I poorly conveyed the challenge to the player. for research purposes could you show me the part you thought was impossible?
