Well, YOU are a pretty redheaded girl :D I mean, if you want to, because, I guess you understood that redheaded girl from cover represents the player themselves! But I feel your disappointment. Maybe, if I decide to continue working on a game, I will do some cutscenes where she will guide a player a bit and compensate?
Yeah, for full version (if there will be), I would definitely do more tracks (by do, I mean I would probably hire the same artist to write one more track).
And regarding the bugs
1) Yes, it is true. Unfortunately, I didn't have the energy and time to fix it completely, so for now, I can only propose to do the hack you did and think about it as part of the narrative - character is angry with you managing them, so sometimes, they behave badly :D
2) It is interesting because level 7 can be passed with only one toggle :) But no, I did use platform behavior, I was just applying force. I can share the source code if you are interested.
Thanks for the very great feedback!
