For some strange reason, the patch that fixed the window from jumping down causes you to not be able to click on levels on the menu.
I have reverted the patch in order to figure out why this is happening. Thank you for your patience - sorry for any inconvenience caused!
Changelog
FIXED - A level was missing music
FIXED - A level's achievement did not work
ROLLED BACK - Window jump fix (this bug will occur for now. More info)
