Interesting concept. But after time game will not be so interesting.

Game design: maybe working more on this game will make it better. Also if you add some AI and career mode, game will be more enjoyable.

Graphics: is simple, but looks good. If you work more on graphics game will pop up from other games.

Overall: game is great, but you have where to grow. Also, please fix bugs.

Bugs: After finishing throws, game is freezing, but you can control camera.(Maybe it's not bug) And I think you should work on turning mechanics, because I think it doesn't work.

Great job. Keep going on!
