Sorry, but I don’t see a potential. Where’s replayability value? How long do you think the player will be interested in pushing and throwing stuff? You could add some special items like timed bombs, which would push players away from it on explosion. Also you could make some tiles disappear overtime so it’d be harder to stay on the platform. Still, i believe it’ll sell only if you market it for kids. And I don’t see it succeeding on kickstarter. But good luck anyway.
