I can grab a material, but I'm unable to do anything with it at the workstations. So I can't make any progress. Also, the music only plays when you go back to the menu, but the cursor gets locked so you can't go back into the game.
Actually, I found out what the problem was. I was downloading it from the itch player, and it only half works from there for some reason. But downloading it manually from Chrome makes it work fine.
