A working pause button. Due to a glitch, the pause button is currently useless; once you press play, the game reveals that it never paused in the first place.

Infinite reincarnations as a reward for solving all puzzles. Once you finish the game, the reincarnation limit no longer serves a purpose.

Fix the delay in collecting finished crafts. Currently, it often takes 30 seconds to a minute (sometimes even 2 minutes) to collect any single product.

Return items from incorrect mixes to the inventory instead of wasting them. It is unfair to lose valuable items simply because you accidentally pressed the wrong buttons.

Trained healers improve their healing ability on their own as often as they improve their other skills.

One of the female voices sounds like an irritated 'huh?' which sounds way too harsh compared to all the other voices. I can't stand that voice, so I temporarily mute my device before picking up villagers who have it. I really hope to see it replaced with a kinder voice.

There is a problem where villagers over-build once their building skill bar is both mastered and filled to the edge. Even if you set their preference to another mastered skill, they frequently maintain huts as if you had set their preference to building. As a result, it becomes impossible for their farming, healing, and/or research skills to surpass their building ones. I hope to see this fixed so there can be more diversity in villagers' most proficient abilities like in real life.
