Hotfix — Achievements, Pause Bug & Level 19

Hey everyone! Looks like I broke a few things while fixing others, sorry about that! This hotfix should get those sorted: Fixed achievements not unlocking. Fixed controls becoming unresponsive after pausing. Leaving the game paused for too long could disable input and force you to restart the game. Fixed Level 19 after restarting. Restarting the level could leave it behaving incorrectly, making it almost impossible to complete. Made minor timing tweaks throughout the game. — ciego
