today I did a big gameplay change even if took just a few lines of code

In practice, a complaint of PS1 was that even if you had the "fuel" bar, which got consumed every time you avoided a random encounter, you could just go back to the colony to refill it without penalty.
Since in this game there's passing time/turns, I added this limitation. Before you could just take 1 day and explore all the maps, skipping all the random encounters you stumbled in because there was no penalty

You could get your overall party health to 0% (all dead in practice!) and you could still explore the maps.
Exploring them all is a big thing since you know exactly where the locations are, and you get bonuses when extracting resources. So, after this change, it won't be so simple anymore...
