This update adds the ingame Shop and the possibility to replay routes to gather more money for the shop. It also lays the groundwork to many future systems and mechanics.
Added ingame Shop with a set of permanent bonus items at "reasonable" prices
Fixed a persistent typo in level name declarations
Added routing systems, allowing to replay levels on higher difficulty (only levels 1 and 2 currently supported)
Improved elevator sequence behaviour
Improved World 6 boss to punish corner sitting. Still needs tuning ^__^
Added sound to crate hits in World 6
Slight balance tweaks on World 2
