What are the distinctions between my 2013 Roblox client and the actual 2013 Roblox client?

This is a comparison between my 2013 Roblox client and the official 2013 Roblox client. If you're interested in playing Roblox from 2013, I used an older Roblox revival called 'Austiblox.' You can play it by following this link: https://austiblox.net. Additionally, if you want to try my 2013 client, you can access it through this link: https://www.roblox.com/games/13026980629. Feel free to ask me any questions, except Robux!
