EastAsiaSoft is at it yet again. Trying to lure in an audience of wayward weeaboos with lite Western Hentai in the form of a half-baked game. The old adage, "Sex Sells" comes to mind often with these types of releases, and I have no doubt it may still very will find it's buyers despite what I'm about to say.
With "Shuttlecock-H" art and gameplay gimmicks are of base level indie design. Almost like asset flips. Low effort material with spicy content included for the thrills. In it the developer reverse engineers the shmup genre, and turns it into a collect-a-thon with a dodgeball focus.
You basically collect groups of five hearts that appear onscreen for a limited time while dodging bullet hell that shoots by faster than your ship is able to move. There's a certain number of hearts to collect per stage, and a certain number of the series of five hearts that must be obtained for that perfect playthrough. Your only ways of achieving this is by dodging bullets, and other hazards while utilizing a boost mechanic that doesn't even seem to work.
