I'm really stuck between a 2 and a 3 and honestly would give this a 2.5 at best.
The content is perfectly fine, it's exactly what you would expect from something that's game and watch but smooth and modernized. It offers a nice variety of all sorts of positions and a few bestiality scenes that kinda feel out of place in my opinion. Theres two hidden horse scenes, as well as a third on the main menu, and at one point you randomly titfuck a bug. Theres a single scene with a slime and other than that it's just Ms. Game & Watch getting fucked in various ways. My only complaint for the most part is the lack of cum animations. It could have really benefited from having an additional part to each scene.
As for the gameplay, well, that's the biggest issue I have. At first it's fine but the longer you play the more annoying it is. The actual platforming is extremely basic and is pretty typical of what you'd see from newer developers. Jumps feel floaty, collision is really weird, jumping off of edges can sometimes be completely unresponsive and overall the game is kinda clunky. Theres also some design flaws I don't particularly agree with such as having way too many leaps of faith which can cause some situations where you think you have to jump before realizing what you need to do and losing a life. An example was in the castle theres a platform that moves left and right above water with a few fish spawning spots and I thought I just had to jump because the water wasn't visible anymore at the platform's height and I thought I just had to leap for it and donk my head on the platform.
One major design flaw I really hate is the whole screen reset on death. The further you get into the level with the levels getting longer the more frustratingly annoying it is to deal with this. Granted the game is pretty easy to avoid taking damage it doesn't change the fact that if you do near the end of a segment then you're going to find yourself running all the way back through everything again. This can be especially annoying when you're doing the option routes while looking for scenes and being sent back to the start before reaching the end and having to redo it all over again only to find a single heart at the end so you just got back what you lost but still wasted all that time.
I would definitely suggest just downloading a save and checking out the gallery because actually playing the game isn't that worth it. As nice as the content is its too far and few in between all the platforming. The game is just way too long and boring and the physics are too clunky. Maybe if there were more enemies and instead of dying and being sent back to the start you were raped/fucked and lost a life but continued where you were right then and there I would bump this up to a 3.
