project: rushing the aether

[THIS IS A VERY BASIC PROTOTYPE, WAS ABANDONED FOR A WHILE. NOT GETTING ANY CHANGES UNTIL I FEEL LIKE IT] Made as a test for myself. Left as open-source since I don't really know what to do with this. (Looking back at this, the code is like really bad. Especially the code that handles all tower functions.) Heavily based off "Aether Rush" by Quantization and some other games. If this was a full game, the progress overall would be: 4%
