The last level Rashay's Moon Cellar exemplifies this, with its 4 subsections (with tight platforms themselves) being connected to the central area with long pipes the player has to balance across that are barely wider than Mario himself.
So many different-themed levels, different powerup caps, and new mechanics! A very fun hack and I can't stress enough how much the upsides eclipse the few downsides, but somehow criticisms are easier to write than praises, so here I go:ฤก) The game difficulty increases as the levels grow mainly by means of the platforms becoming progressively smaller as the levels go on and therefore more easy to fall off of.
