It is a great idea, and I agree with the other comments that with time and work put on the polishing and more ''showing'' it would be a whole 5 star game. I just must say I was super confused at first, as in what was I? Was I the white cube or? And such. Also even though the objects are bright red and big, it was very hard and overall near impossible to see and dodge :O But other than that keep it up!

While not the most polished of games this is a great concept and with some more work could be a great game keep it up.

To build on what Bruno said, the obstacles could do with appearing earlier than they do, since I do not have enough time to react to the obstacles. As well as this, I went to far left and fell out of the map.

If I must be honest, this game is clearly hasn't had your best efforts and could use some polishing. Though I have no experience creating games I must say that you could probably make it easier to see the objects ahead of you. More specifically, I mean the blocks that appear on the left and right while moving back and forth. Sometimes one would come straight at me with no warning whatsoever. Just an instant death. I do like your game though and even took an effort to beat it. Good job.
