Update v20180321:
Levels
Following feedback from the community levels 4d, 5a, 5b, 5c and 5d have received some slight changes to their layout. They have all maintained their theme and identity, however some of those unnecessarily frustrating jumps and platforms have been replaced with more negotiable ones. They by no means make the levels cake-walks, but they shouldn't be nearly as bad to complete. Let us know how you go with them!

Bugs
No More Magic Carpet
Removed Frame-Perfect bug where you could fly...Seriously...
Level Times Show Properly
Fixed issue where your set time wasn't always displaying correctly on the time screen.
Prevented Level Restart Glitch
Removed ability to get insanely low times through a glitch/skip
Playing Falling Forever
So it seems we left some holes in some levels, hopefully this time we've fixed them all.
