Thanks to all the reports so far, everyone! I was able to fix all the typos, small visual glitches and do a couple of tweaks here and there. Keep reporting if you find anything weird!

-Fixed typos
-Fixed all sorts of visual errors
-Fixed the ui world colour not always updating when using the level select to travel between levels
-Fixed a couple of level layouts where it was possible to get stuck too easily
-Fixed not being able to return to the red candy from a later checkpoint
-Tweaked timed platform readability
-Tweaked swimming controls so that jump doesn't override the down button
