yeah so i heard some of you had your save file deleted by the new update

because in order to add the challange levels i needed to overhaul the whole level code.
didnt find a way to prevent that. i apoligize.

but to make up for it i made a secret code to unlock your lost progress by pressing

ctrl+space+shift+R

(hold all together then add the R) then reload the save

tell me in this's discussion if it solves it or not.
