This is so good! Really like the character glow lighting, great sprite and it brings it alive. The puzzles that use reset are quite clever since you have to "die" to progress. Nice scene transitions and mist chasing. Not sure if the enemies work though, maybe they should just reset you to the start of the screen you entered thus slowing you down and letting the mist catch up vs instant game over? They can appear & move pretty sudden so the instant game overs are a bit of a drag when otherwise messing up only costs you time as the mist catches up. Alternatively checkpoints could help, like one right before the first enemy.
