Still in the intro and this dev may have the worst priority I've seen so far in an AVN. So much useless time wasting. Why would anyone think an unskippable 10 second timer is a good way to portray the passage of time? Possibly the dumbest "feature" in any game I've ever played.
Seems all but...
Webm is for videos. You may be thinking of webp.
MP3 is ancient garbage. OGG sounds better at lower bitrates. Opus is even better again, but not as widely supported yet.
Grain is harder to compress but the noise indicated the dev just doesn't know what they're doing.
From reading the comments, it seems the game is moving in a direction I'm not at all interested (NTR). Shame, as the older daughter may be the most attractive model I've ever seen, but oh well.
Are the models available anywhere?
