I really do NOT appreciate this sort of game. You can easily betray the trust of players, especially in a game jam, when you pull things like that, especially with the super high volume.
The build up of tension and the story up until the end was really well done, but that ending was upsetting and ruined the experience for me.
I know I'm not the target audience, but this sort of game feature needs to be something that players opt into, not happen upon in a game jam.
Still, congrats on your first game jam and submitting something. I just wish I could have enjoyed it more.
