Acorn Arcade Review The basic idea of the game Swarm is to fly a little jetpacker around the screen and collect all of the crystals to complete the level. Also, to make the game a little harder there are of course some bad guys and mines dotted around the playing area. The baddies come in all sorts of shapes and sizes, some just follow you around the screen, others fire at you but luckily you do have a gun to get rid of them. This game is about the only one out of those reviewed in this mag which I have completed, well, I say completed, but then again it just crashed and returned me to the desktop after about level 46 so I presume this was because it had ran out of levels. This really annoyed me because I had spent a whole afternoon trying to complete it, hoping for a nice congratulations screen!
