Detana is a Solid SHMUP. I like Twinbee series. its' different frantic and challenging and has a cool upgrade system that is imo what makes the game. The Turbografx 16 version is even harder than the NES due to a lot of clever enemy units. It has some creative boss fights. Stages have unique looks. But overall the Playstyle and mechanics is similar to original, if not the same. Music and sound has some familiar famicom konami-klick type old school sound but sounds decent enough. bad things It's understandably short, its also a bit unreasonably hard imo. It's not a large leap beyond the simple nes formula, its tough to reccomend it since its an oldish and aged take on a game thats QUITE old. It is however on the other hand, a much nicer version of that game. I played the T16/PCE and Saturn version of Detana (above) back to back. I personally like the look of the PCE, and think it sounds better (the Saturn has nicer quality of sound but it isnt mixed as nicely together, if that maks sense) Playing the game it admittedly feels a bit smoother of the saturn version.

Yahhoo however is a very different story (and game)
