Not sure if all the comments are from PC/Android/etc, but on Mac it seems to be very buggy.
I love the characters, writing, the gameplay style and the graphics are really unique.
Jak causes a lot of bugs in my games. Even if he's dead, he'll still burn everyone's house down if I sleep with them AND he can appear in jail (but he's dead so stays there forever). This is more or less an issue since the characters' interactivity creates a lot of the gameplay. When this happens, the game stalls and there's not much you can do to progress.
In general, I think the game needs a bit more direction. You mostly wander around with very limited areas, but you can dead-end yourself as well and never know. It's a bit hard to tell progression or change. Open-ended is fine to a point, but it's pretty confusing in a text-based game.
