Thanks for playing and the feedback! I wasn't aware of the Firepunch negative PP bug, I'll fix that up and have a QoL update done tonight.
The other specials aren't active so they can't be purchased and their options don't do anything. I did have it so the colors were grayed out when you didn't own the skills but for some reason my project reset a bunch of settings on me like 30 minutes before the deadline so i missed a few things. I'll get that sorted too!
And yeah Hilda is supposed to be strong, and you need to play a few times in order to get enough stats to stand a chance. In a future releases and in the spirit of the JSK games these are based on there will be additional phases, and she'll get even stronger in each. I'll tweak her stats a bit though. I'll add some audio as well in the near future to give a bit more life to the project.
Thanks again for playing!
