I would give it 5 stars but sometimes I get stuck on the loading screen THEN I would have to reinstall it again. But that's not all when i'm on teams with my friends just chilling in RHS (Robloxian High School) and I have to type in the toys (gears) inventory and THEN ONCE IM DONE TYPING my screen on ONLY on Roblox starts very quickly changing its brightness from -1 level to +2 levels. Anyways with that aside Roblox is AMAZING AND YOU SHOULD DOWNLOAD IT!!!
