Sorry but I don't think the file you've provided is actually playable. You need more than a .phz to be able to execute it.
The file is for the app algodoo. When you download the file it directs you to Algodoo and pulls up the scene
Most people, including myself, don't have it installed. Like with Roblox games, few people will play and rate this game if they need a special program to open it.
that's my bad. Also, the game isn't good anyways, so I dont expect it to do well at all. But next year im gonna use Unity.
