Really neat game! The core concept of your health being synced with your environment is really unique and the introduction of many different ways to "desync" the two in order to solve puzzles is great.
I think there's a lot of potential for even more levels here and would love to play through an expanded post-jam version!
There was one minor glitch where I could pass through a wall tile. Was the intention of this puzzle to allow you to walk through the tile? I only stumbled upon this since I couldn't figure out any other way to complete the level.
