Bugs and balance tweaks!

A few more bugs have successfully been squashed! I'm afraid this won't be the last patch though, so I'll stay vigilant.
Additionally, a few balance tweaks have been made to make certain playthroughs possible/easier. Amongst this, the last 18 levels have been adapted to make certain modes much more playable and function how they're supposed to.
In the coming updates, I will make balance tweaks to the new levels, as well as generally finalizing the level's design before moving on to more exciting, new content.
