I think it's at least 3 stars so i'm gonna try to up your rating a bit with the extra 2, I like the mechanics of this game, brick animation and score tabe. My advice is change the timing of the bricks because they come down in the center fast right before a wall obliterates you. And maybe add a cool bg and character.

A score board or keeping time would make this game interesting as well as adding new features to make it harder. It has potential.

In regards to the author comments, no it's not that obvious. More importantly, this game has no sense accomplishment or fear. The screen just reloading doesn't make me feel defeated. A simple "you lose", or "Ha! You lose BOI!" would help. Some music, sound effects. Things of that nature. The graphics are simplistic. It looks more like you've developed an engine than a game.

I'm pretty sure if you dressed this up with music, sound effects, a points/score system, a preloader, menu, credits, lose screen, win screen, and some levels, this'd be a fine game. Feel free to browse NG's audio portal for royalty free music. Feel free to use my musc ;) Thanks for sharing and keep practicing!

The red thing that you're supposed to duck under goes way too fast for you to really react quick enough.
And the buttons for moving the square are way too far apart on computer.
Maybe not label your games as amazing when none of your games have even demonstrated themselves to be at all "amazing".
Please improve your skills until you feel as if you can make a better than mediocre product then post what you can come up with.
I'd like to see what you could make with actual skill. -Daniel
