I'm the guy who decompiled the new unity game and plan on working on it after I get back from home. I have few easy features that I would want to add to Demon Remaster, this "seems" easy, might try to add button to reverse the images or something. Don't excpect it in this week tho, I'm getting back to my flat where I have PC with that project around next weekend. I have recharged a bit and will propably get back into it.
Someone also asked me for Kouhai apk. I'm not big fan of the futa myself, but I might try to make APK in a similar way I did the beta for Demon Remaster if the exporting won't get fucky. Will make it also just h scene viewer with everything unlocked for now, won't bother with story mode/combat.
