Simply wonderful!
I'd expound on the perfection of the story-telling and atmosphere, for it's genre, or the fact that it's of an enjoyable complexity while not quite violating the time-frame or difficulty of a "casual" game; but others have done that.
The execution and mouse-friendly refinements of the interface are proof that you can make a fine story-drive RPG with RPGmaker, use standard assets and all, yet provide a damn fine playing experience! It's the difference between diddling on a keyboard and listening to a concert pianist, and you certainly set the high bar for RPGmaker craftsmanship.
The glitches remaining are minor, and I wouldn't complain about them except that it might actually help you, so here goes:
- The worst glitch is that the game progressively gets slower over hours of play, and eventually crashes on an out-of-memory error or some sort of missing pointer reference (probably to an asset that failed to load, due to memory exceptions, as it _always crashes while loading a battle, a scene transition, or a "top-level" map.)
I suspect you have a memory leak in the combat screens, assets you don't dispose of properly after the battle or some such thing. It's a fairly common error. The leak might also be in the round-robin menu and it's sub-menu screens, but my sense of the noticeable slow-downs would send me to the battle code, first.
- You disable the relationship score menu, to hide the X-rated aspect of the game, except that it appears once in the tutorial texts, and all the relationship changes are announced, and gifting is still enabled. I'd leave the relationship menu and dialogs in there, and just have a "curtain" graphic where the sexy cut-scenes should be, that way you don't have to seek out and pull the dating sim mechanics out of the game.
- The "shift" key battle speed-up is interesting, but I'd appreciate it be homologued to the centre-mouse-button for mouse-only play. Same for the jump button. Same for the only scroll-down menu, the fight options in the battle routine.
Yours is quality work, and I salute you!
