Currently there is a issue with lag, but 0.9 is suppose to fix that. I truly love the game and all the systems there is a lot of effort put into it even if it is on Roblox. Roblox games normally have tons of passes and are cash-grabs this is one of the few that you can play and even beat entirely FTP. If you haven't tried the game, give it a shot before you knock it for being on Roblox.
