Really nice game , very interesting puzzles and design choices. One bug I found is in level 3.3, the door only opens, when you push the block into the pit and does not always work, when it's standing on the shutter dropping down on the lever.
Yep, I found this issue while watching a streamer play the game.
The puzzle should play correctly on the first run, but if you restart the level with something pressing the button it'll break. Work around for now is to exit to the level select and reload it.
