DieFeen is an alright vertical shooter by the creator of Visionary Wings, though this particular production features 3D enemies and backgrounds much like those found in the Shikigami no Shiro series. The title refers to little fairy creatures which act as options, surrounding your character and offering some protection from the hail of bullets usually prominent in most doujin shmups.

You can retrieve up to four of these fairies from your inventory at the press of a key, and switch their formations around at any time. They will have their own health indicators, which are depleted whenever a bullet hits any of them.

Still only a Comiket 71 release at this time, though a full version will be made available in the next expo.
