It sucks. The gameplay is rough, for a shmup, controls shouldn't be like this. The ship is way too fast, and there's really no way to slow down except for precise use of the joystick, which is pretty much impossible if you're trying to snap to a different direction to dodge bullets as fast as possible.
There's little variety in the gameplay, which is a bore. The same enemies, the same patterns of bullets, same patterns of enemies, and if they want to make it harder just drop 150 more enemies. The gun for the ship sucks, and there's no second weapon you can use.
Then, there's the clothes. Stripping away character clothes is not something new in here, there's one out there with the same mechanic, but I'd rather not name. But if the devs did use that as a point of inspiration for that mechanic, they did not work it right. The giantess flails around uncontrollably without any sort of telegraphing, making it hard to strip her in one go. And I'd say you need to do so, if you want to avoid waiting with your dick in your hand for 5 minutes for the next opportunity to hit like 20 damage out of 100. This stripping mechanic, is unavoidable. You NEED to strip her 100% to actually finish the stage. Tedious to play with, especially with lack of firepower.
The art is fine. Despite the unique 80s artstyle, but nothing really pops out about the game itself. From the giantesses, the characters, the ship and the scenes... Nothing that really strikes me as cool, but I guess some erotic stuff here and there. The giantesses seem thematically misplaced though, they look like they come from a fantasy.
The story... uh. I felt like I couldn't be bothered. It feels like it's just tying a rope to a chainlink to a guitar string. Nothing wrong with a story like so, since porn is what we're looking for here, but if it wasn't, this just feels like another piece of tedium that adds onto the tedious gameplay, it just made me feel like I wanted to get it finish it quick.
The porn? There are couple of scenes, from what I've seen, but it's easy to just skip over it by a click. It's just there for the sake of being there, and feels like more emphasis was put on the Giantesses rather than the sex scenes (there's 2 so far from what I've seen), and the naked Giantesses are only accessible through the slog that is the gameplay, there's no gallery access to it. I would nitpick that you have to rip off specific clothes that would add to the naked giantesses, a bit of a shame, but I digress.
Overall, at the least, some work needed for the gallery so the porn stuff gets a focus. Wish the gameplay was better still.
