This is the most unenjoyable experience I've had trying to 100% a game in a while because of this DLC.
Yes, I get it's "supposed to be janky thats the joke!! Don't you get the joke!!!" but when I've had to restart the game over 3 times just trying to craft all of the items ONCE on one round of survival due to the game breaking bugs then I'm gonna get frustrated. I was using casual mode too, I can't even imagine trying to play this buggy garbage of a DLC with actual survival on. On standard Goat sim levels there's a restart and respawn option for a reason, things just break sometimes, but you can't do that here without losing all of your progress that normal maps either don't have or save automatically like in Goat MMO.
The map is lackluster compared to other maps, the survival mechanics are annoying when you can die for reasons beyond your control because this is Goat Sim and physics tend to stop working occasionally, and there's just not a lot of interesting content. If you're going on a nostalgia trip for Goat Sim or are just looking to buy the game for this reason, don't buy this DLC unless you want the achievements and even then get it on sale, it's not worth the 5 USD it's asking for.
