This is a pretty fun and original (unless someone has done something like it before) "time waster" type game. Perhaps the menu buttons could use a bit more style that matches the 3d style of the game.
As for the laggy comment below, it runs fine for me so the lag could be caused by a "not-fast-enough" computer or perhaps browser issue.
A simple, but smooth and pretty addicting idea! I wish there were some highscores, or finite goal, or something to incentivize further climbing, but as far as the game goes: I like it! Creative and catchy, and easy to play and replay. Good game.

I really like it. It's great in it's simplicity and does actually look original to me. I'm a strong fan of games that try to show some kind of original mechanics, so that's a big plus from me. On the other hand, it's just a simple game that doesn't even encourage me to come back to it. It's not wrong, but it's not amazing either.
i like how the blocks get cut nice idea mm
It is a good intepretation of an old, but everlasting concept :) Maybe just add a lil' bit of music and a little more colourful text / index page :)
