There will be a sub weapon with at more defensive utility. It's not a dodge, but it can be used to help position for cranking undisturbed. Different combinations of relics can also enhance different play styles. Other than that, the core combat loop will more or less be what you see in the demo.
Interesting. Roughly how many times did you upgrade AP? Don't think I've coded max caps for the stats yet, but I thought the GUI would break or crash the game if a player upgraded too much.
Edit: Took me way longer to figure out than it should've. The code seemed fine, but I had mixed up maxPlayerAP with maxPlayerHP and I didn't see the typo at first. Thanks for reporting. :)
