havent read any comments so dunno the specifics on the "complaints about the scenes being too long" thing but i thought id give my 2 cents atleast..
first off: you have an impressive ammount of scenes considering the few releases that have been made, i played the 0.2 demo and after playing for like an hour or so i ended up playing for many more hours expecting to see a "end of demo" message or whatever to pop up at every turn but was pleasantly surprised by a lack there of, and unlike many other low version releases you actually have proper content and not just a bunch of teasers that goes on for many months until any real sexual content is added and you even have endings, mighty fine dev model so far in my opinion.
second: the scenes are not too long, its more like some of them includes parts that id rather skip for... revisiting purposes, yeah... so if you could find a way to cut up some scenes into 2-3 pieces with a bit of return to the world where you could save closer to the action i would be happy, or add a replay gallery? with the few save slots in rpgmaker a replay gallery is the preferable choice, like in Beggar Of Nets "The New Life" i have 3 save folders to keep track of all the unique scenes i felt a need to revisit because of no replay gallery(i guess i could get around that by downloading the cg pack instead but..)
