Summary: If you enjoy Space Harrier, Galaxy Force, or Star Fox, then this game will appeal to you. It has elements of all those games (some of the level design is clearly referencing Galaxy Force in particular). Graphics are wonderful, really showcasing the GBA's remarkable capabilities and colour palette; 3D tunnels, day turning to night (and vice versa), flying amongst the clouds, you name it. Sound is just pure bliss for anyone with a love of retro games.
Summary: I already got the amazing Gradius Advance and wanted another shoot em up to add to the collection. Fans of the genre should like this game. It plays a bit like Space Harrier (remember that?). Once you slap the cartridge in and turn on you immediately sense that you're in for something special. The graphics are truly AMAZING and the soundtracks are FABULOUS (and there's lots of them!). The developers have really seen the potential of the GBA and it shows in this game.
