really nice game, I loved the pixel art and the gameplay/puzzles are brain-melting, I encountered two small bugs, one where the spike block had no collision and allowed me to cheat my way out, and also occasionally the level would restart when I reach the final door and win it?
besides those minor issues, and sick work you have here, the title screen is gorgeous and also the transition between the levels is a nice touch
congratulation on your submission and best of luck!
