Thanks for the feedback. Really apprec the detail of it. 1 and 4 seem like easy fix I'll work on it and upload new build asap. About 3 the lag is probably caused by physics I'll probably need to lessen the pellet count. And about 4 I know about the poor player experience the option is there mainly for testing on my slow laptop but I'll think about making the quality bit better.
so the updated build with fixes should be up
