I don't know what you did with the perspective but the hardest part is actually telling when and where you'll pass through the blocks.

Could really be something. Very good start. But it does not feel like a game yet.

I have to say I've never encountered this control scheme before.

It would be more intuitive if there were left and right in addition to rotation. But maybe that's the point?

Cool game, but maybe you could add more stuff to the landscape so it's not just a deserted place. I think it'd make things look better visually. Maybe more obstacles, like cacti.
