Interesting idea for health being tied to standing still, but i feel like it doesn't match up well with the puzzle concept. The keep moving in this game ends up being a chore while you figure out the puzzle instead of being additive to the gameplay. Also the 1 puzzle was pretty simple, It would've been nice to see you do more with the block/button/door mechanic you made. Visually, it would've been nice to see a little movement/animation from the character, but I do like the cohesive color palette
