I have a solution for those who are struggling with the game. I play the game on Windows 10 so I don't know if it works for other system. Go to your windows setting, go to the "hour and language" option, then in the left panel you go to "Region" and finally change your Format Region to Japan. You do not need to change your country to Japan and it doesn't change the language of your computer so don't worry about navigating in a system where everything is written in kanji.

Before figuring that out I also added Japanese as a optional language to my keyboard setting, ran the game as administrator and mess with the compatibility option to emulate an older Windows. I do not believe these last three actions helped me to make it works but I am informing you that I did those things just in case one of them actually helped me in some way without my knowledge.

Oh and don't forget to switch back your Region Format to what it was once you are done playing.

The game doesn't work properly: there is no sound and music, character can't attack (there is glitched animation) and walk normally (it crouches all the time). Also no fullscreen option. Tried it on Win7 with both keyboard and X360 controller.
Unplayable at the moment.
EDIT: Solved by changing Region to Japan. See Tazok comment. F4 for fullscreen.

i like that game and the other from the libra heart series .didn't had bug so im ok with it

Solid game. You can definitely tell it takes inspiration from Castlevania. Took me about 10 hours to 100% the game. Pixel art is very clean and the designs are nice. Only complaint I have is that I’d like to see a bit more difficulty. Definitely checking out more games from this publisher. Solid 8.

This was really enjoyable metroidvania GAME (not strictly fap material).
However, there's DX version by the same author/publisher available on Steam containing bugfixes, autosave option and alternative soundtrack and it works without changing Region/Time zone like this version (FAKKU version was not updated).
If You don't mind getting "naughty" games in Your Steam library, buy it there.

This is overall a solid metroidvania. Gameplay is fun, controls are simple. It's very reminiscent of the old Castlevania games, deliberately so. Sprites are well made and look nice (yes, even the naughty ones). My only complaint about this game is that it's very easy to get lost at times and not know where to go. I've heard other people have had bugs and issues with the game, but I've never run into anything like that. But other than the one issue, this game is definitely worth the price.

good game but the controls are all SPREAD across the keyboard (you couldent put it all in the left or right hand? really? but spread that shit EVERYWHERE BUT THE WASD KEYS!?)

Man, I would love to see more uncensored platform games like this one or better.

Works fine on my windows 10 with my 360 clone controller. Press F4 to change screen size, even full screen.

Same problem, do something, plase!
