Found this nice little gem currently free on iTunes for 2 days. Just released by Lightworx. Have installed it & had a quick go & its a good arkanoid/break-out clone with space invaders mixed in! Strange combo I know but after a couple of levels does seem well worth a download as its FREE. Would I pay for this if it was 59p - NO to be honest its not as polished as some of the apps on iTunes (ie gameloft, ea, glu titles etc...) but for FREE can't complain.
The little 'un just tried it & he seems to like it - probably as its such a simple game to play (bat 'n' ball).
