SIRIUSLY LAGGY! NEEDS TO BE FIXED! The pklayer controller is hard to control. I think the source code should be realeased or modding and mapping.
How you mean laggy? Is your system reach the minimum req? Try to lower the graphics from the options menu!
And yeah this is an early access version therefore I'm fixing bugs you guys reporting. :)
The source code wont be public soon, that's sure. Maybe after I released the game on all mayor platforms. Maybe next year... we'll see. honestly, i dont have plan for that.
