Thanks for the kind words and feedback! Glad you enjoyed it :)
We had planned for the shop management aspect of the game to be more fleshed out, but we ended up having to cut back on it a bit due to time XD Once the jam's over we're planning to at the very least patch the issues we know about, but if we end up looking into releasing a fuller version of this game then we might end up looking back into the shop management stuff again (and possibly adding more impactful choices) :) We'll have a look into the issue you've noticed around the books resetting if you restart the day (think that's a new one! XD), and we'll look into the safe interaction/experience as well to see if we can improve that too. Regarding the purpose of the stuff in the safe, it's just lore that ties into the hooded figure's storyline as you've suggested (it's not a critical piece though) :)
Thanks for playing! :D
