So spending quite a lot of time and making a hard decision,  The game will be really limited in visual fidelity.
You can expect these few things:

Locked at 720p (Due to me that cant code post-processing stuff) 

No Vsync - The game has to run at a stable 60fps as the animation and physics are tied to this.

SSD is required due to sound and animation streaming.

The engine I use is Range Engine. It's based on the old Blender game engine, and there are a lot of technical hurdles to optimize and make things work compared to Unreal or Unity.

I do apologize, but hopefully the experience is still there.

Estimated Requirements:
GTX1060+
8GB Ram
i5 CPU

Currently this game runs somewhat smoothly on my MX150, but a solid 60FPS is definitely needed.
Love yall, and see you soon!
