I really liked the dual nature of the game with the focus on building yourself an optimal path with as few objects as possible and then racing through it. The leaderboard was a really nice touch. As far as feedback goes, I think the mechanics could be better explained, it took me a little while to fully understand the process.
As far as presentation goes, I mean the game just has so much style. I really loved the dynamic shadows from the boxes, and the light trails, but honestly it was all pretty.
Very cool, nice work.
