If you want, I can send you a decompiled project version of v0.87
It has everything up to the current released update, though I understand that it will still mean a lot of lost data.
I deeply recommend that you continue this project. I think with proper work and advertising that this could genuinely be the next big RPG Maker hit. I made a post about the game a few days ago and within a few hours it had garnered a lot of attention on Twitter. It'll be hard, but I still recommend that you do it.
Being able to look onto your finished work, that finished game project, is absolutely worth it.
All of that being said, I absolutely understand if you need to take a break from development. A loss like this is unbelievably hard to deal with, and you should take some time to rest and recuperate.
