Great concept, but the 2 things that killed it for me were the sound effects and not having up arrow also rotate the pieces. Now that I type it I'm not sure where I learned up = rotate, but it would have been a welcome feature.
Cool concept, cool music, but not incredibly playable -- do the same colors stay with the same shapes always? If not, mixing that up and adding more colors/shapes would help.
I gave up at 249; expand this game enough to get badges and it'll be a big winner. If and when you do, keep the threshold for success / moving on fairly reasonable, let people challenge themselves by going for the highest scores or harder badges.
5/5 because it sucked me in enough to play all the way through. Reminds me of the game Pooyan with the wolves and the pigs and the arrows. It needs more bosses, breaks, and maybe tweak the timing of when the powerups refuel.
3/5 -- I really enjoyed myself on the first board, and the concept of finding numbers instead of differences. But the second board felt like dirty pool (that is, the level wasn't fair) with how dark everything was. The music was good enough, but the sound FX could have been chosen slightly better.
