Really great! I like the fact that you can test-run the level before you actually do it. One thing that'd make it better would be a quick-reset button to go back to the start. Other than that, great little game!
Thank you for playing my game! The idea of putting a time limit came precisely because you could practice the level before playing it. There is a key to restart the same level which is the “R”, it appears in the controls of the website itself but I forgot to put it inside the game.
