Maybe take a look at Left in the Dark? Right now it is just going to be the prologue and not the full planned version, but it should still be interesting. though, art wise, it is likely not going to be in a entirely complete state for the jam... I trust in the fact it won't look bad though. Haven't seen anything from the dev in a bit, but I trust in them managing to work things out.
In the final version I do plan to have voice acting in the game, and in fact am planning to voice act the main character myself, so If this stream is done at the right time, I could TRY to be a guest to do that voice acting. My internet isn't THAT great though, so I am not sure how well it would work.
Once It is up I will provide a link if you want!
