I played through the Demo, and I loved it. This so far the best RPG Maker tickle game I have played. If you keep up this level of quality, I will definitely buy the full version.
I would like to give you some small suggestions for future developments:
- If possible, there should be a way to speed up scenes and dialogues we already went through. If someone wanted to watch a specific scene again, this would make it much easier to reach it.
- I didn't have a problem with the puzzles, but just in case, you might want to implement a 'cheat' option for those, who do have a problem. I don't think they were hard, but many people, who buy these kinds of games, want to rush to the scenes.
- I don't know how this game is going to end, but if it's open, it would be great if there are multiple endings. Perhaps one where Marywell ends up locked away in a dungeon, being tickle tortured forever (The Bad Ending). Another great feature would be a Sandbox mode at the end or after competing the game, allowing one to roam around and to either experience any kind of tickle torture or torturing other characters (Or this could another Ending like The Neutral or The Good Ending). But this last point is just a suggestion, and I wouldn't blame you if your plans for the game do not allow these ideas.
