Storm Caliber is another example of the well made shooters which are being developed in Japan. Exciting to play and with a wealth of power-ups and interesting graphics and sounds, the game will keep you going until you discover that it only has 4 levels. Unfortunately that is its only limitation since you get to the last level and past the final boss pretty quickly.
The developer has tried to keep interest in the game going, by hosting an online rankings table, that way people played for the score rather than just to finish the game. The ranking system is no longer running however, so enjoy what you can of the Storm Caliber and hope that someone sets up independent online high-score rankings in order to spice things up for players.
A short download for a very fun game, definitely worth the 5-10 seconds you will need to get it.
