Looks like you had fun making your demo, all good practice. Was enjoyable rolling around and jumping and avoiding the edge to the music.

Next thing I would do is try to deal with the camera clipping into the ground. Keep working on it :)

Nice music choice, the terrain took a little while to load in but was fun jumping around!

Would be really fun for the whole game if there was stuff to destroy, maybe a bowling ball and not a basketball? For heavy damage or more towers to knock down. 

Was fun, took a while for the terrain to load but it's a browser thing.

It seemed more of a toy than a game, but as you said it is unfinished. I'm curious how you intended to turn it from a toy into a game. What kind of goals would the player have and what sort of obstacles do you imagine to those goals?
