Really enjoyed playing! Literally my only issue is the Sound Design which obviously I'm gonna be more critical because I'm a Sound Designer and it's like a curse that I notice things that nobody cares about lol.
I think just a couple of corrections that could improve this would be just mild pitch variations for a couple of sounds as they become repetitive and other little things like making the players movement fade when stopping as it noticeably cuts out. I also dislike the jump sound.
Some sounds also feel out of place like the big magnetic blocks make sounds when hitting the top of the magnet machines but the sounds are completely mono and centre, so if the player is on the other side of the room is sounds like its right in next to the player even though it's not.
Some objects also feel like they don't have as much weight as they should. Like pulling both a small and big pipe cover sound the exact same even though there is a clear size difference.
Besides that, visuals amazing, puzzles are REALLY FUN! And I can't wait for the full version to release.
