Winner of the special prize in Microsoft XNA Game Software Contest 2010 in Japan, this SHMUP just released on the Indie Service is a true gem. It's new take on the genre consists of a "twist" game mechanic that allows the player to also dodge the bullets with the triggers. The traditional 2D plan of the SHMUP games becomes 3D.
This is what the developer (kuroro) has to say about his game :
A horizontal scrolling & revolving shooter. Revolve and dodge the bullet hell!! 2 game mode,trophy system,and global scoreboards.
Better than explanations, just try it (it's free) and don't forget to use the rating system so good Live Indie games stand above crap.
