Just played with my girlfriend and we both had fun even though she doesn't play much video games !
Very nice menus and art, music also fits well with the atmosphere.
We felt it would be great to have some extra lives to make it a bit more forgivable and make it even more enjoyable :) The fact to switch seamlessly between levels was great though, it doesn't feel like you stop the action at any point.
Working for a multiplayer game within such a short period of time must have been difficult but you have definitely done a great job ! Congratulations !
