Played in one sitting, 8 hours
Only played through the entire story and a bit of 21. There's one thing in 21 that is an absolute time waster of a gimmick that I can only recommend to play the Roblox equivalent of this gamemode coincidentally called Twenty One.

Generally, it's good. Quality, runs pretty well even on what you'd call.. 2013 hardware?
Story's alright, never been a lore nerd so it wasn't a high priority. Would entice someone else though.
