Returning player here! I played from the start again, and liked all the changes I could identify were made to 0.1 content, imo they all improve the game - and the script is in perfect English now, congratulations on the improvements!
0.2 keeps the story going in an interesting direction, I'm looking forward to seeing how things develop! Now, I played 2.1 rather than 2.2, but I had no problem with the minigames, though I have a suggestion on something that I see 2.2 didn't affect: if at all possible, on the spot the difference stages there should be a counter, displaying how many differences you have left to find.
Also, was the dance even winneable in the first place? I see you lowered the winning conditions "from 60 to 50", yet a perfect run seems to give you a max of 56. And I did get a To Be Continued screen, if you win the game continues?
Also, I didn't see any of the scenes in the gallery on my playthrough, yet only Elysia showed up as "Not on Route" in the stat tracker (after deciding to talk rather than attack), is the rest working as intended? (I'm talking about the route tracker status for the heroines still showing "on route" despite already having missed scenes) EDIT: Thinking about it, the choices are a point you should be congratulated on - most AVNs have extremely obvious choices, of the type "be kind/be rude", yet here "the right choice" to stay on a girl's path or see all her content isn't that obvious, and at least to me it is refreshing to see.
