- "restart the story" : no worries, if done as 'New Game +' you will have the old one and the new one, and can switch between them at your own desire.
- "drinking milk cup..rarest" : actually all 4 special events are cycling one after the other, Halloween is as rare as Surprise (milk cup) event. It's probably because it's the last one in cycle that it seems more rare.
- "there is a chance that the animation won't triggered" : thnx for the info. If you would bump into previous or other bugs feel free to notify me (preferably with steps to reproduce the bug).
- "fairy event" : sorry i never worked with RPG maker engine, and sadly haven't played the game that you described. The inspiration for this was probably some doujinshi (really great for fetish-like inspirations) and my own imagination. What i described is supposed to be just their hostility towards a human (their attack animation, same as current Harpy forced crotch lick). I'll reveal more details when i'll get this part in development.
