Another thing is that when you pause and go to the main menu, it doesn't let you click play again without refreshing, and since it doesn't save, you have to start from level 1 again
I hate the new level editor for Pr3. Well, not hate it, but...I'd rather have it nice and simple, just like this. Not 5 things to click, scroll, etc just for getting 1 type of block :/. But it will go better with the level, though. But Pr2 level editor is better, imo.
