Bug fixes

Been ill this week so haven't been able to go full steam ahead, so only minor bugfixes this time.

The minor bugs fixed for the PoC version:

• Timer can't go over 60 now
• Timer and game over panel borders now fixed
• Grabbing for rotation anchor now smoother, no popping movement in edge cases (which were distracting and felt buggy)
• Different aspect ratios should work fine now
