I really liked the animation, it was very well done, but I thought it was basically 2.5 minutes of grunting and screeching, then a funny ending.

I really, really like this game, but it is way too laggy on my laptop.

I think this has decent potential, but what it really needs is a sense of progress.

There's only one level, so it gets really boring. Maybe try changing the sets of numbers spawned or the size of the stage at various scores. It also doesn't help that the graphics are really drab. Even if you only added a nicer border and colored the tiles according to their number it would be so much better.

Finally, the music doesn't work for me.
