Indie Game Nation fixes

I went to the Indie Game Nation to display my game, it was cool, got lots of useful feedback. Moving on to the obligatory bugs-that-never-appeared-before-but-did-several-times-during-the-event-on-seemingly-random-occasions-and-which-make-me-want-to-kill-myself, I started working on some fixes, all's not done yet though. 

-attempted a fix for preventing the dash to glitch through walls when the window wasn't in default size

-fixed switches able to be pressed while chest is being carried

-fixed galathea's bubble veil not starting on the right of the arena

-fixed hippodjinn unable to be picked when using custom keys

-fixed several sharks spawning from the first spawner in bubbly way

-level design tweaks to the first 2 levels
