i guess when... designing the platforming.. you felt like.. having the player slide around like they were on ice was... good design?

Tetrominoes should snap to a grid. This way they wouldn't stack so easily and the player can predict the falling more accurately.

I really wanted to like this game. It's a simple idea with stimulating gameplay. However, it suffers from massive flaws. If you stand under the "hook" of an L block it kills you when you destroy it even though there's nothing above it. The block hit detection is way bigger than the animation. The jump attack feels sluggish and doesn't allow you to reposition from falling blocks. The highscore doesn't work (at least for me) and the list goes on.
Good idea but really, really poorly executed gameplay wise. I like the music though

there is an bug when hit the L block the player die for no reason.(sorry my bad english)

It's pretty good, and a perfect idea; somehow, though, the controls are weird for me. I just can't get used to Z as jump and X as attack, I keep swording when I mean to jump...It's nearly impossible for me to jump up to hit a block...
