SPOILER:
I reached Level 50, now a countdown is running down from 2,147,475,... Can I end the game finally ?! PLEASE answer...I am waiting!
hey! its actually a bug that this occurs, theres supposed to be some special secret stuff that happens every 25 levels, atm it soft locks the game. If you want to progress further you'll need to find an elevator on the previous level to skip the softlock.
and PS, there is no end, it is truly infinite
