Totally over-difficulty, not a well thought out 4 player mode that can go on for hours if at least one player survives the level, the rest just wait and stare at the screen. Impenetrable even the first boss. The game has strange physics: when you go to the right, you stop, and the character himself goes a little to the left. Jumps sometimes need to be measured in pixels so as not to die. She's not even worth the discount price.
