One of the better games of it's kind around, no doubt.
The graphics are pretty nice, with adorable characters and colorful areas. I do think it's worth noting though that some of the background elements are actually 3d models, which can clash a bit with the rest of the scene, though it might be a matter of taste. I'd also like to mention the background music is quite chill most of the time, and sound effects are typical for this type of game. Not much more to add there.
The gameplay here is actually quite good, and has more RPG elements than you might expect. You've got item farming, upgrade crafting, and levelling up your active skills with Skill Points. More in-depth than usual for side-scrollers, though admittedly grindy by design. While there are many skills to use in combat, I do find controls somewhat clunky and unresponsive at times. I wouldn't call it a deal breaker most of the time, but something to keep in mind.
A cute feature I really liked is how you can "befriend" every enemy you fight, and befriending said enemies boosts some of your stats, and lets you have your way with them whenever you encounter them, if you wish. They also have individual names (though they look the same) and can also visit your town, which is a nice touch.
Don't have much to say about the story, though I would say it's mostly light-hearted fluff. The characters are all cute, and even the more "r*pey/femdom" scenes are usually relatively gentle and consensual, which can be a good or bad thing depending on you tastes.
The H-scenes are a bit simple, but also well-done and plentiful, with dominant and submissive variants. It seems a lot of attention was given to the male "fluid", if that's your thing.
All in all, a pleasant surprise. Easily worth a shot if you enjoy Oneechan X Shota, Monster Girls and ero-platformers/RPGs in general.
