Updated to v0.8.1

Hellooooooo again.

A lot of changes but no content, so...keeping on 0.8.1. Pretty much everything changed was aesthetic:

• The boost bar is...actually a bar now. No more "boost meter: x/200." It's split into a left and right section. The right section represents your boost, and the left is the cooldown. If you didn't realize boosting had a cooldown when you stopped, well now you know :)
• Boosting itself now causes you to glow and light up the immediate surroundings
• The level finish has an actual sprite instead of just being a generic placeholder green circle
• The camera's horizontal movement is now clamped so it stops at the left and right wall

I think that's all the changes...I don't see anything else in my git commit history. Anway! That's all for now. Consider leaving some feedback if you have any, and I'll see you in the next update.
