decent
decent lights out clone, i guess it's lights on in this case though.
you have a pretty solid start here, but it's horribly underdone.
sounds and maybe an animation for the on/off change would definetly help this a bit, but if you add music, don't try to promote your sister's friend's dogs shitty garage band and DO let people mute it.
i also think a tutorial level to explain the basic concept and lesser obvious mechanics to players would be good too, the handheld version of this game gave templates for certain block arrangements and how to solve them in it's manual and that would be good here too possibly.
6/10 stars and 3/5 vote.
