I just released my latest App yesterday!
You can play with up to 4 Players on one iPad and as I already said your aim is to blow up your friends and be the only player who survived.
There are also some Power-Ups spawning after you destroyed a block, so for example you can increase the Radius of your Bombs with a Power-Up or you could maybe get an additional bomb.
But don't forget to pay attention not to run into a bomb or fall into the water!
You can buy iBombU for just $0.99 on the AppStore: http://itunes.apple.com/us/app/ibombu/id464418092?l=de&ls=1&mt=8
I hope you like this App and if you buy this App and like it I would really appreciate a review on the AppStore.
