13 levels of pushing blocks in front of lasers. A lot could have been done with this setup and different kinds of things to push, but most of the levels are pretty easy. The last level doesn't even follow the game's own rules, requiring you to walk in front of a fake laser and step on an unmarked switch that silently turns off the laser guarding the key, without indicating that it did this whatsoever. The graphics are also pretty garish and sloppy (not that they matter a whole lot in a game like this, but the presentation was off-putting). This game might have worked if more thought was put into the level design and the graphics were more competent.
