well here is my console log, just in case u need
(ignore the part where it says I have aimbot. ;) )
if you know its against the rules remove it. it also doesn't seem to say in the console, so you've literally just admitted to having an aimbot without even any proof of you having one being there.
just so you know, even suggesting you have blhack or aimbots or wallhacks gets you permabanned from forums, and straight up proof can get your key revoked. despite this not being a terribly competitive game, badspot takes cheating seriously, as you should too.
that said, your window seems to keep refreshing the graphics - it seems to do this every time you click into blockland after clicking on a program outside of it. i'm fairly sure this is due to fullscreen - try switching to windowed and seeing if that helps. fullscreen games tend to just freeze or work very slowly when put into the background.
