Really clever puzzle design! Cool vibe as well! As for feedback, I think you could rearrange the levels a bit, the last level honestly was one of if not the easiest and the ending didn't feel as climactic as it could have if the game finished with a harder level imo. Overall though the game's great! 

Cool mechanic, I think it could use something more like a teleporter or conveyor belt (with a different flavor) or something like that, but the puzzles were well made and I liked the aesthetic. Good job!
