The rating being 2.5 stars (at the time of writing this review) is criminal. This game may not be as good as the best of the best side scrollers, but is it still leagues ahead of the average H-game, thus my 5 star rating.
I'll first address some of the negatives that other reviewers addressed and then I will give my own summary.
Bugs:
I did not encounter a single bug during my entire playthrough. I also played the official version from DLSite, so that may be why. It at least seems that all bugs that other reviewers described have been fixed.
Difficulty:
I completed the game on Very Hard difficulty on my first playthrough without ever having to grind EXP. One boss took quite a few attempts, but everything else went pretty smoothly. The game becomes significantly easier when played on Easy or Normal. Everyone should be able to beat the game regardless of skill level.
If you die to a boss, you respawn right next to it. You can respec for free, so you can always attempt different builds if needed. Certain builds turn all bosses into complete jokes even on Very Hard.
Combat Jank:
This game's combat is inspired by Sekiro, but it ignored some of the core design choices of Sekiro, resulting in the combat being a bit weird at first. Like in Sekiro, you can deflect most attacks. But unlike Sekiro, your deflect has a wind up animation. This means you have to use your deflect right before you get hit. Also unlike Sekiro, you cannot animation cancel your basic attack by deflecting. This means the entire wind down of the attack animation must play out before you start deflecting.
These things combined make it feel as though you get hit even though you deflected. Once you get used to it, it is still a fun combat system though. But the combat is also significantly slower than Sekiro, as you can't just spam basic attacks and then react to the boss. You must instead always ensure that you have time to finish your attack animation and then complete your deflect wind up animation before you get hit.
As for enemy wind up animations, some of them are pretty bad. But due to the forgiving respawn points and short cuts, it never becomes frustrating before you learn their attacks.
You can also just jump over most attacks. I almost only deflected against bosses and a handful of enemies.
Level Design:
The areas are a bit too big for my liking, but it is still tolerable. They aren't quite as big as to commit the "giant empty levels" sin that often occurs in this genre.
If you find certain enemies frustrating, then you can just run past most enemies. Sometimes you are forced into combat, but if you just have a good build and you focus the annoying enemy, then this should never be a problem for you.
There are two or three cheekily placed traps, but other than that almost all traps are completely visible and are not frustrating. If you enter youkai form, then all traps get a red highlight, making them impossible to accidentally step into.
H-content:
All scenes are animated and high quality. Though some enemies' "H-attacks" are just grapple animations with no penetration.
The total enemy variety and scene amount is ok. Could be better, but it is by no means bad.
During defeat scenes, you control the pace of the scene by pressing M, or whatever the "cancel" keybind is for you.
There isn't really any corruption.
Summary:
A very solid game with some rough edges. Most problems that others have expressed have either been completely fixed (or least fixed in the official version) or can easily be circumvented by just playing on Easy difficulty. This game is definitely worth your time if things such as no-corruption isn't a deal breaker for you.
