While I don't mind the idea of a Roblox game, I don't want to go through downloading it to play your game. Roblox is great in it's own environment but outside that, it's not convenient for run and go experiences. If you're interested in game design, there's a lot of great (free) software out there to your disposal (Unity, UE4, or even something like RPG Maker...) Take the time to learn one (or more) and the experience will be rewarding.
