Ask any mad scientist worth his fortress of evil: lasers are awesome, shark-mounted or otherwise. This has been the basis for many a shoot-em-up game (see our Hyperwave review for a good example) but they've been lamentably absent from the puzzle genre, until now. OverLight uses a series of lasers and prisms to mix up the conventions of falling block and match-3 puzzles, with no small amount of visual flair. It's available now on Google Play for one dollar.
Lasers can come from all four directions, heating up and eventually breaking the glass panels, but not before being redirected through them.
