Thanks for playing! and for all the feedback. I am totally hearing you out, will try my best to fix the issues that made friction for you, specially the puzzles.
Also, if you are having problems with controls, plz play it with a controller, a gamepad thumbstick has 360 degrees rotation support which this game is made for, while the arrow keys only are restricted directions. The keyboard support is only there for the players to have a rough idea of whats going on, and is not the original way to play it.
