Opinions thus far:
-It's actually a game. Things attack you, you have to dodge and fight stuff and get around obstacles.
-Feels moderately polished! Small technical details like holding arrow keys while attacking scoots the heroine in that direction.
-Great high resolution pixel art scenes, that is of course animated. Including the fights with the 5 succubi characters that want the girldick or something.
-Excellent heroine attack pyrotechnics, love the way the spell dissolves into the seams of tiling and grates.
-Cutscene CG filler for the 5 succubi characters.
-No story, no lore, things are kept simple for better or worse.
-Kinda buggy. UI translation issues that make no sense, getting caught by the grate slime twice will mess up your character's movement from then onward.
-Strange lean towards squishing the heroine under things, although thankfully they don't get actually crushed or cartoon flattened.
-No gallery, no way to view animations without getting to a particular area
-Fast travelling is difficult, all the levels have the same graphic and fast travelling to a place with a cutscene means you'll have to sit through it again.
-No way to skip cutscenes, it's so annoying!
-Slime area seems to have a lot of scene differences for most enemies based on addiction level. Sadly this does not seem to carry out of that level.
-Moderately short, maybe an hour's gameplay?
-Most content you deal with outside of bosses is pretty damn easy to beat or get by.
-Pretty expensive for such a short game. But hey at least it's moderately polished and not just a gallery filler.
Would I recommend this? Maybe on sale or with a coupon, content-wise it's kind of short and that sticks out quite a bit. There's much better futanari games out there like Setaria, which has prolly thrice the content at less than half the cost.
