We actually played this as a two player game and it was super fun!  We played several times, learning the physics of it, improving our strategy, and laughing.  Well done!  What was the inspiration or precedents for this idea?

Good Entry in the end. I like the idea, the delivery lacks some improvements, as you can guess. But good job!

Good effort, certainly if you're just starting with Unity. The game design was pretty decent for the time given, if worked on and polished it could be a fun online multiplayer concept. One tip (maybe it's just me), but making a 3D project that doesn't need the default skybox, I just turn it off in Rendering/Lighting Settings (select 'none' under the environment tab). Generally good job on the game, and have fun in your further learning Unity! :) 

pretty good for someone starting out with unity (coming from someone who's spent forever trying to get it to work lol)! it feels a little weird to use arrow keys with the mouse instead of wasd though, and i think some music and sound effects could greatly enhance your final product :)
