(Devlog addon) Oh, just another thing, if you want to download the new update then you will have to delete the old version (put it in the trash) THEN download the new update, unless you want to keep all versions of the game to show your kids XD. Also on Mac (I don't know how to do this on Windows) but if it says "2DPlatformer.dmg could not open because it's from an unidentified developer" then go to system settings > security and privacy > General then click 'Allow'. Hopefully that will help you. Enjoy!
