I found a bug and I think it bricked my save file.
Warning spoilers ahead.
So after going to sleep and gaining my first skill point, if I go back to Ember's and eavesdrop backroom again, then the basement location disappears from my map and when I go back to my apartament the 'Purple Gal' event starts all over again and I get to sleep again gaining another skill point. Now, I had some fun and unlocked all skills ahead of time but now after continuing the story I have a skill point to use but there is no skill to be unlocked so I'm stuck and can't continue.
I'm playing the linux version v0.7
Also love the game!
Yep, that's a bug. Turns out the condition that's supposed to lock you out of that branch doesn't actually get checked. Whoops!
You could un-brick your save file by opening it in a text editor and setting one of your skills to false, that way you can get past the screen. (Or start a new one.) In the meantime I'm going to push a hotfix for the web version, since that's a game-breaking bug. Sorry and thanks for the report!
