Huh, that's actually more expensive than I'd have thought for a single bulb, even taking into account that you'd probably only be running it for a quarter of the time
It's been a few years since I tried it out but I think following these instructions on an Ubuntu machine worked without any problems. From there you just copy the binary to your Deck and add it as a non-Steam game as normal (making sure to use the Linux runtime rather than Proton).
I think this is something a lot of people posting here don't get. You can be a programmer, make apps or games in your spare time, set your own goals and be your own boss, and that's great. Suddenly you get a "normal" job programming and you have you deal with customer requirements, business nonsense, and working as part of a team; that's being a software engineer. One isn't superior to the other, they are just different beasts.
Android sandboxes apps anyway, what GrapheneOS does is allow you to install Google Play Services in a sandbox so you can use it without granting it the admin-level permissions it usually demands.
I have often though about what ridiculously high rolls in 5e would look like. I think rolling a 30 in Performance would be Freddie Mercury at Live Aid.
I completed Afterbirth and put it down for a few years, I've recently got Repentance and not only did I pick it up again pretty quickly but there is so much new stuff. I can't recommend it enough!
