I think it would be a great idea to gather some good minds behind project. I wish I could contribute but I’m only a max 2 year C++ programmer with no idea how to do graphics programming. Yes Unreal would review your git submissions and you could always message one of unreal devs on twitter or directly message them on here to see what they’d recommend for submitting stuff for review. If you can get a group together to start improving paper2d lmk, at very least I’d like to test and provide feedback.
