Thanks for playing! You can't get soft-locked because if you're out of money, you get a free pity ticket =). Similar for crashing if you have no money, it's not game over. For viewing instructions, yeah, Itch's "fullscreen" is a bit weird on the setup, but the back button on your browser will get you there (just make sure you save, I'm not 100% certain itch won't unload the game... or actually the back button will first navigate to my main menu which probably isn't desired here).
For the final NPC, it auto-saves before the choice, so you can simply click "load game" after making a choice to get back if needed.
% completion would have been a good idea, that probably would have made a better leaderboard secondary factor than the nebulous/grindable "wealth"...
