I liked the idea of a timer countdown affecting the game state, rather than being an immediate loss — like, instead of shutting down with a game over, you're introduced with a new complication. Needing to manually press the arrow keys every time instead of holding them down was also an interesting choice, I had some exciting moments where I was hammering right, trying to make it to the exit in time. Always good to have a player rethink the basics that we take for granted!
