love the idea. there is so much potential. I would love to see you expand on it!
However, I often felt out of control, not knowing when the time runs out or when the level restarts and the timer automatically starts running. The timer could have a progress bar - strong visual and audio feedback.
I also thought about a timer that only runs while you're moving?! You could let the player hold a button to let time pass while standing still - this would give the player more control shifting the focus more on the puzzle rather on a speedrun.
Really cool game! Let me know if you keep developing it!
