unknown error wtf

I can't complete 13 lvl cuz of controls bug. In that lvl you need fast jump and switch the worlds. 1st phase is ez, but when platform goes backwards, you cant switch worlds, if you press +[left arrow]+ in the same time. Actually this bug occur in all lvls, not just 13. yes, i'm playing on keyboard... Dev, pls fix that...

How to replay the last level after completing the game ? :o
