Mindless platforming ftw. Coin collecting addiction fueled.
But you've gotta fix that glitch where the whole screen just goes black at the start of a new level. I gave up after it happened to me 3 times (twice after the starter frame for the 2nd level and once after the starter frame for the 3rd level)
If you can't fix it, at least add autosave so that we don't have to repeat all of the previous levels.
