I approve of this game!

I think the 3rd chapter is a little bugged.
The cumming animation takes like 5 minutes. Cant skip it.

 

[Riltom]

the animations seens bugged to me, taking reference on the animation that appear on the menu and the one on actual gameplay it seens parts of the animations does not play properly, the audio also seen to not play properly.
Like the blowjob scene most the time the sister does not move her head for like 20 seconds and then suddenly she appears to be with her head in another position.

Any voyeur stuff?

It sucks that there are games like this that fail to be good. The game is very boring, at least in my opinion, because it has no sound, not a sighing sound or the girl's voice, because it really sucks. This game could have been a pleasure to play, in my opinion, and I would have enjoyed it more.

There are sounds, unfortunately the game is very unoptimised and the animations stutter, lag and slow down the game's workings to a near halt. I hope the dev fixes these issues because there is potential here.

I like these kinds of games. But as already said, it seems to be very buggy in the sex scene.

Try to speed it up with Cheat Engine's speedhack function, works fine.

 

[MaximusAnalus]

Where's that uncensored patch?

 

[xmilteach]

thx

Actually pretty daymn good game.
Surprised to see something wholesome.

About bugs, dunno, did not got any throughout my playthrough.

One key note though - if you want text to go faster, set it to MIN instead MAX.
(As long as they are not finished talking you won't be able to continue your activates)
I dunno why but these monochrome games sometimes flip settings values, so in the end fast is slow and slow is fast...
¯\_(ツ)_/¯

Pretty nice, but a lot of the actions don't seem to have animations, which is quite disapointing.

 

[Gaias]

Cute game, love these monochrome titles.
