I have to admit, the countdown being used for both the level making and for playing the level itself is very clever. It really makes you consider and think critically. Do you make the level harder but give yourself more time, or do you make it easier but get less time?
The game is a bit short, and I can’t play the 4th level for some reason (Maybe it’s the same as level 3 from the thumbnail?), but nonetheless, I find the mechanic creative and I think there’s a lot of potential in this game
