Yes, there's a way, but cheating is bad. I only do it for fun (challenges) or just looking around the maps in versions or just mess around with it. StartBeta = unlock every level. Use a15 because the level costs 1000 dcoins and not 9999.

Where is a15? I don't see it, the reason why I commented that I wanted to cheat in the game, is because the jumpscares are so scary, I beaten the school level by doing a glitch, where viktor falls down a hole, for the school level its so scary and hard, it feels like beating stereo madness on the first level, and then bloodbath on the second level, and on the third floor it looks like a grandpa demon level.
