Good game! I liked the minimalist design, but it was VERY minimalist, without any art or sound effects. And as there is no description or tutorial, it took me a while to understand that I could double jump, I could grab the blocks (it's a really cool mechanic but I found the grab jump too low) and I should go up. It got to a part where the code wasn't well thought out and it was impossible to pass, causing me to lose and have to wait to get to the red platform. But the mechanics in general were very creative, with the blocks coming down and you trying to climb up!

I liked the the way that the difficulty increased, it's simple overall but pretty clever to link it to the height you reach. The movement is also surprisingly deep, having to manage double jumps and wall jumps. It's reminiscent of flash games I used to play as a kid lol, I could see this doing well as a mobile game. I like it. I'd love to see it with some graphics.

I feel it needs more visual feedback on the background, to show that the cubes are descending. After a 30 points record or so, visually i cant determine if im far away from the floor or not, only by the numbers in the corner which is kinda far away.
