A more open approach has been taken for this update to Wiggity Wings. The normal difficulties for Worlds 1, 2, and 3 have been unlocked!
There are still hard modes to unlock for these each of these worlds, as well as three secret modes that change up the game experience quite a bit. However, instead of having to go through the main levels in order, you can now pick which world you want to start out with.
And be sure to check out the Wiggity Wings soundtrack on Bandcamp.
