I know you wanna say, ofcose we all here need say thx to Dev for his beatifull project,
waht not have alternative in whole porno world games,
but.... I just not undestend how work this egine, if every times, old saves do not wanna work?
Is a custom engine, so if in the code he found something for example, causing lag, errors, updates in somenthing, etc, when he change that code, that conflict in the save (saves use old code), i cannot tell 100% of why because i don't have access to the changes in the code. Now at least, he said that he probably was one of the last updates that he can see in the future for the engine, so in the next update and forward, save will be compatible. That don't happen a lot in some "normal" games (renpy, rpg maker, unity, etc) because they are already done with the engine, is just putting stuff in them (renders, sound, story, etc). The last problem for example in renpy was when they changed from 32 to 64, there was a lot of bugs in the engine.
