Upon playing this game, the first thing you notice is the extreme similarity to Caverns. The game is mostly tried-and-true MZX builtin stuff, so if you like classic MZX games, this might prove to be fun to you. The gameplay is good old shooter style, so I give it some points there. But the graphics are either standard MZX or that wall character, spare a few others. Also, the music is - you guessed it - from Caverns. If you happen to have a major liking for this 'genre', it is worth a quick skim.
