I remember I used to get stuck in ALL the paths, but playing recently I've managed to beat all three without walkthrough!
I appreciate the weird and mysterious futuristic vibe you're going with your games, BUT they would improve a lot more if you added descriptions that hinted what things do and how would they be usefull for the escape (like a commentary like "it looks like this transmatter machine can recreate a copy of whatever you put in the left if you put some material in the right")
