I think it could run pretty easily on mobile, maybe if you make a "lite" edition where you use less shaders and textures, because even after lowering renders on my pc the game is super laggy and annoying asf, even turning around has a big delay
At this point I don't really even think it's all that much to do with the graphics, but more with the physics engine, the ragdoll tends to chew up quite a bit of compute. I'm actually in the process right now of upgrading all of our dependencies and the engine itself, if you follow along in the discord, I'll release a tech demo for the new systems in a week or two, would love to get your feedback!
