Not bad at all. Some varried bgs might be nice. There's a glitch in the score: after you die and start over again, after your first action it counts from your last score. Also, I'm playing in browser for a reason: not everyone has a TB of space to waste. 3/5
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz... huh, what? Oh, there's 'sposed to be something constructive here... ... Well... the music is soothing... :S... 0/5
... On the one hand, it took me six months after MC was developed to find out about it or even like the idea. So someone not knowing and making the exact same game could very well be possible.
On the other hand, Minecraft it damned-near memetic, to the point where people have taken already established memes and applying it to MC.
Conclusion: there's no real excuse. Nice try, but do some research next time... and render an actual sky instead of a still photo with clouds. Looks funky. 0/5
Too cute. Sound and music grates the nerves horribly. And even after I stopped that noise, it's just a plain arkanoid with nothing to set it apart other than the incredible ability to create headaches out of nowhere. 1/5
