The game felt outright primitive across the board - non-existing story, no gameplay mechanics to speak of, by extension no strategy even hinted at, but the deadpan voiceover was what made me check DLSite page to make sure, and indeed: "Partial AI use" tag with clarification in the description that "this work partially uses AI (accessories, background, translation)".
Also, there is no futa content whatsoever: the white-haired boss uses tentacles, the winged demon girl has a magically-attached strapon, and the purple enemy in the screenshots has a dildo-tipped tail.
Random tidbit: game keeps saves in AppData\LocalLow\Agasii魂 , with hokan1 being the save data and kankyou being the config file (in-game settings like controls, graphics, etc.).
