I'm the developer of That Stupid Game and been working on it for about 2.5 years now. I also brought friends on board to do audio & music, video editing, playtesting, voiceover and steam capsule art.
There are a number of unique mechanics including the ability to go into first person with a rocket launcher! It's not yet publicly available, but will likely do a playtest with the discord community in the coming months. Also happy to answer any questions if anyone has.
