it is a neat idea but it is hard to tell what is happening at first. a formal menu or something would go along way as it didn't make a lot of sense why you start the game needing to press n to start a new game. It would be nice if the levels were guaranteed to not just trap you immediately, a lot of the levels seem to have stuff below where the player can see and often times where the loops are and the size of the belt make a lot of the level feel meaningless especially if only 1 loop is possible. I'd recommend having more carefully designed levels rather than procedurally generated ones (which I presume is the case for the levels) as it could drastically increase enjoyment if the levels feel satisfying.
