What prompt did you get?
I obtained "Bleak Scraps a 2d20 game for 2-5 players". I like sci-fi so I immediatly think of some space adventure involving orbital junk. I was experimenting with a system (a creation of mine) that uses two counterposed dice (d6) and I adapted for the d20. I know that exist a commercial 2d20 system but I wanted something different. I hope that the game will be appreciated

Is your entry a TTRPG, or can it be used with a TTRPG?
