Thanks a lot for your feedback! Yes I get frustrated with the puzzles myself lol... We wanted to add a top down view and make the puzzle stones and gaps more clear but we didn't have enough time to polish that aspect sadly. Bringing a 2D shuffle puzzle in a 3D game sounded fun at first but our implementation wasn't the best. You can play without suffocating by unchecking the checkbox in the beginning but that seems to not be clear enough as well. Thank you for playing for so long. (the timer is 15 mins:))
