Done for the night
Alright, just one more day to work on this! The core gameplay loop is now working, with infinite waves where the baddies get stronger and more frequent and you need more energy, etc. Now I'm working on a shop to hopefully make these waves more and more possible!

Right now it'll just go forever, especially considering there's no lose state. Should I add a final wave? What should happen afterwards? idk, we'll see if I have time to deal with that tomorrow. I've still got to implement the shop items, and add some more enemy types.
