Update V0.0.4.1

A new semester finished, and a new full version released.  With this, we've added some of the new UI, re-added the ranged character, and fixed some bugs like, say, the ability to move between levels.  (Life is pain and suffering...  But at least only the other students tried that version.)

I make no promises that this is perfect right now, I'm currently so completely burnt out that it took nearly an hour replace one button, but it's functional at least.

I'm keeping this a general update until I have enough energy to say literally anything more about this...  I think next week I'm going to do a bit more bugfixing, and then release a major update for it getting out of the v0.0.4 beta...
