I love this so far!
I told my brother about it, and he's not really into using PCs so he tried to download it on Android. Seems there is an app there called 'Stick it to the Stickman' - with graphics that make it look like this game. But it downloads a pretty naff jigsaw game instead.
I don't know if this is a glitch, an honest mistake, or someone trying to scam people based on how amazing this game is so far.
Just thought you'd like to know.
