This game has the potential to become a really good tosser, but there's two things that are keeping it back, namely:
1. Lack of colissions. There's so few things you can encounter at ground level that once you're under a certain height the run has basically ended. At higher points it's better, but still not good enough. It's far too common to finish a throw without impacting against anything.
2. Lack of saving feature. Seriously, I wouldn't mind the slower pace, but having to redo all from the beggining every time is absolutely unnacceptable in a game like this.
If you could fix those two things, this game would be a 9/10 for me.
