I'm simply amazed that a shooting game of this quality could be made on the GBA. This is a masterpiece vertical scrolling STG for the GBA, developed by Shin'en. It was created by a development staff who love Japanese shooting games. The familiar direction is an homage to Japanese STGs. Despite being packed with such homages, it shows a wonderful cohesion. From the visuals and direction, I feel that it has a strong influence from Treasure's "Radiant Silvergun". By the way, the previous work, "Iridion", is not a vertical STG, but a 3D STG. This is also a masterpiece! And as a successor to this work, the DS "Nanostray" series was born. With the improved hardware performance, it has evolved dramatically, with cool polygon-heavy direction. It reached its completed form with the sequel "Nanostray 2". In Japan, "Nanostray" was released under the strange title "Danjaku". It is an essential work when talking about DS shooting games. And the person who handles all the music for this series is Mr. Manfred Linzner. The music is all exciting and hot, stimulating the shooting spirit, and it's wonderful! Especially around the time of "Iridion II", the songs were also lively and the best. Also, by the way, the BGM for the 3DS series work "Nano Assault" does not have music provided by Mr. Manfred Linzner, but he only participated in the supervision. But there's no need to be pessimistic, as this also has a great selection of songs.
