Oh wow, okay thank you for all of the finds. I'll try to respond to everything in just one comment but forgive me if I missed anything!
1. I found the issue with hardcore mode. Instead of turning ON all lewd events, it mistakenly shuts off the ones considered tame. I will correct it in the next update (which will combine the PT version with the older style demo.)
2. Anything listed as a free action is a holdover from the prior builds before the combat system was reworked. Hopefully all of that will be removed by the next update and we'll firmly be in 2.0 territory.
3. Yes, B can be used to activate Blink. This is kind of an easter egg that you found. It was something I was considering adding to the game but wasn't quite sure about. In the end while the game never tells you that the skill exists, I ended up leaving it in this build just for fun. Having since explored the mechanic more with my jam game Alice In! I think this skill really needs to be built around, and can't simply be added in like dashing and jumping. So it likely will not survive to the final build unless I find a way to make it feel useful without also being stupidly broken.
4. Whoops! That was a major oversight. I totally forgot to clear the lighting when using the teleport skill. I'll update the skill to fix that as well. Since the lighting is effectively just images on top of the screen, various events may or may not clear the displayed images, so the event you triggered probably just happened to have the right code to fix it.
Thanks so much for all the feedback! It's greatly appreciated.
