Ahah nice!
Yeah from saying a few peoples play I think I should add a couple more tutorials to make some stuff clearer.
If you get to the pink biome, you are pretty much done, especially since I forgot to turn on the ore generation there despite what the "end of demo" popup says ^^'
If you get at the bottom of the first biome and aren't strong enough, you get teleported back up, so people shouldn't get stuck usually.
(Need to use charge shot on the "door" to get teleported tho)
Thanks for playing! :)
