Highly sparse, could be very interesting to expand on.
And, being about hackers modders and speedrunners, making fan expansions to the game would actually be pretty fitting!
Also, Cloud's Edge "being unstable at the best of times" feels unsupported by the mechanics, maybe a cheatless roll should have some small chance to lower stability despite being a cheatless roll...?
Likely better seen as a core to build onto than as purely standalone as-is, though definitely playable and most probably set to be enjoyable for anyone who'd bother reading the comments on it at all.
Maybe could even theme the fan expands around DLC or somesuch, for theming's sake.
Edit: On further reflection: Failing a roll, whether cheating or not, could be a -1 Stability, to reflect the "unstable at the best of times" aspect, passing with a cheat could have no Stability effect, and passing Cheatless can be a +1. Flavourwise, success would be either getting lucky with Stability (cheatless) or managing to barely hold the game together while doing a bypass (cheating)
Also: can have it so you can do a Cheat roll against 7 minus Current Stability to bump the Stability by 2, maybe? Not 100% on this.
I do feel that there should definitely be a way for a failed roll to affect Stability ever.
