I don't know, it's not immediate to tell. So far nobody complained about RAM problems, so I suppose 8GB of RAM is not a requirement for this map. 4GB (The game's minimum requirements) should be good.
Hey, I'm sorry for this huge bump, I just wanted to thank you for this map! It's so good and simple, and still works till this day. Im playing this map since 2014 and it is always with me in every single beam build since then. Again, thanks for it! Your maps are really good and always make me happy to play it.
