Your sharing a lot of ideas with me where I feel some of those could work well, and you are explaining things clearer now where I felt in the presentation of the game they weren't as clear. If it was just the amount of time given I understand, I think it was a good time length for the game jam so I'd just keep taking those ideas and like you want to try and spend more time, the time you feel needed, to get them across better, but I have more to say about all this.
Developers know more than players do at all times but the idea, or trick, is to try and see it from the player's perspective to see if it's been presented in a way they can see that, I think that is something to just show more clearly. You can keep creating something with a mature theme included if you want to, but in my thinking and from my understanding I think it would be better to create something more light hearted (in the sense of without those themes for now, doesn't have to be a light-hearted project but I would recommend that too) without those themes for now, I think that may help you get more people interested in a game and get better feedback there and then later you'd be able to cover those themes better, but that's just my thinking it sounds right to me but you may want to challenge yourself and do more mature themes anyway.
My issue was, either the game is a bit too pessimistic in how it was handling the themes or it wasn't the objective to do that but it came across that way. If it was purposely pessimistic there are other ways to create feelings of shock or "wow, that's serious, ok." without it being "Oh, that's really uncomfortable I don't want to keep going with this game", if that makes sense? If the aim wasn't to present something pessimistic then the goal needs to be to realise how it looks to a player.
To me it felt like well the person you mentioned a lot was being portrayed in a bad light and that just didn't feel right to me at all. You wanted to create an alter version of the person I think, but it just it comes across as something not nice to that person and that isn't going to be received very well if that's the direction things goes which is why I'm giving this feedback now. Too many of the ideas came across as portraying them in a bad light unfairly, or it looked that way.
That was my biggest issue, but your right to say the themes you used can easily cause someone to feel uncomfortable, which is my second reason why I'm giving all this feedback I'm giving here. I hope that can make enough sense and help you with what you decide to do next, but good luck. I can also tell this may have come across as very sensitive but it's not been given to insult your project but to give feedback as in helpful advice or how to avoid issues. But anyway, good luck with what you do next. : )
