Greetings! I was very happy to see this had an update!
Although, I'm not sure what you did when swapping engines, but now it wont start at all, due to a "memory allocation" problem, according to a 3rd party program i use.
My rig says your game is pulling 8-10gigs of ram on start up, and it proceeds to crash without opening, and it does not give me a crash report or error message that i can post for you.
Im very confused why this program needs that much computing power on startup, let alone playing the game itself. But im not a game dev.
I look forward to a patch that will allow me to enjoy your creation in the near future.
Be well <3
