I found a bug. If you try to make a limbful larry generator (or in any sort of generator), test the stage, when the limbful larry spawns it will cause the game to come up with this error:
also, not really a bug per se but it seems their is some code leftover with the goombill where it will cause a number to appear in the top left coner:
Another thing with the goombill. It will die of a fireball and lava normally... but if it's been turned over on it's back it is invunerable to these things. Not really sure this is intended.
