What an entry! Probably the best one I've played so far, this Stephen's Sausage Roll homage make me realise how utter useless my 3d spatial vision is, I felt like I was completing most of the levels by pure brute force lol. The only bad thing I can mention of is the difficulty curve of the game, it felt a little inconsistent as sometimes I spent 15+ minutes trying to solve a puzzle, and then be done with the next one in less than 5 minutes. But maybe you do need that sense of easy-to-achieve progress to not give up?
Other than that, the visuals and sound are a perfect match for this type of game, and it must had been fun somehow cause I spend almost an hour banging my head against this thing =P
Outstanding job!
