Ahh. I finished the end of the game (current) I got the Philosopher Stone and the Cheater Ring. It said to promise not to use it in the next game. Can I keep them to the next, or will it disappear?
Thank you for playing! It's been helpful to get some feedback. As for those cheating items, there's no consequence to using them. It's more of a recommendation, because when the final version of the game releases they'll take the challenge out of the last couple hours. I don't think I'll remove them in the final version though, consider it a reward for finishing early.
Speaking of which, the ending is planned for release by the end of 2021. I'm the only developer and have a full-time job, so it'll be at least half a year. But as soon as the final version is complete I'll upload it here, so keep an eye on this page this page next winter.
He should've given you a key item called Rail Clue Sheet. Using it will give hints on where to dig in the desert to find the three pieces of the map. All three are in ruins in the desert, so look for screens with broken walls and tiles, then use a shovel in places that fit the clue sheet's descriptions. Once you have all three map pieces you can return to Rail outside the inn at night.
