Probably fed up of these by now, but staring at this willing solutions to appear is getting me nowhere >_<
Only issue is that my code is pretty long, and im not entirely sure what parts to post. for now, heres the main section, theres also some classes but hopefully the problems here somewhere =/
(also, yes, more aliens)

Ill definitely have a read of that and see if i can spot anything!
