I downloaded it a few days ago. I don't play it much, maybe 15-20 minutes every time, since the game consist in entering every room and destroy all the enemies, I don't think I could play it more time without getting bored. I'm not a native english speaker but it seemed to me the translation could use a revision. The art is very nice, Montano looks cool. The music is nice too.
The game works smoothly on my tablet, it doesn't slowdown and it's very light compared to other games. Only 9mb, I've downloaded much bigger games in minutes, and my Internet connection is not fast.
