This is a nice little homebrew shooter album and it's about what you would expect. The instrumentation is well enough (in contrast to a lot of other albums, which are harsher and haven't held up well) and the arrangements are fine but the tracks do come off a bit simple at times. I do like the little sirens in E.I.G.H.T., though, which are a nice touch. Overall, I'd say 7.5/10.
Better Tracks: Continue BGM, S.I.X> (Readme File Bgm), No.15 (Unused 2)
Also Good: S.E.V.E.N. (dreamy), F.I.V.E. (Stage 3), No.11 (Ending Bgm)
