New content:

Added 5 new "EX" levels that are much harder than the main game. You can access them in the level select menu.

I recommend playing them in order because they build on top of each other. The last level is the final challenge in the game and is stupidly hard, so don't feel like you HAVE to beat it. There is also no reward for beating the levels aside from the satisfaction of beating them.
