I don't know how difficult it is or how much you have to sacrifice from the business side. but one thing that makes a game unique is the sound effects. I would like there to be a way to create your own sounds and upload them to our projects. I propose that each project has a limit on uploading audio, since I know how storage on servers works.
I have used different graphics engines but this is the best of all.
A quality job, my congratulations to the whole team.
