I think you need to make optimization for your game.
Yep, a few people have said this and it is something I am actively working on. I have a pretty powerful pc, so I could only test it on my hardware, which runs the game well. It's my first time making something on this scale, so optimisation is new to me, however the performance should be better for the next build, and will progressively get better with each build.
Any chance you could tell me your PC specs too? Would be greatly appreciated.
Thanks for your feedback, means a lot. :)
