The game looks really cool, but as someone with bad english it was a little bit hard to understand the voicemails and I didn't went very far :/ If you continue developing the game (it's your plan if I understood correctly some of your comments here, and I wholeheartedly agree with that plan!) consider adding subtitles as well.

No need to apologize, it's a game jam, it's normal to not have the time to do everything. I just wanted to let you know that it is something to consider for a full game (but I guess you probably already knew it). I wish you good luck for the work ahead of you! I followed the game, but I don't know itch.io, so I don't really know what "following a game" means. I hope I'll get notified when there will be news about it!
