1.The dial of the gas burner would actually require only three modes. Off (temperature drop), heating but maintaining temperature, heating condition
-> Good temperature control may also be a feature of simulation games and an important factor in making alcohol, but the game can get tired of maintaining a certain temperature for a long time.

2. Timer
-> It is necessary to set the desired time and proceed with that much time, which is similar to the above reason. (I think you can put it in as an element that you can buy and use later.)C) It's a good idea

3. Interpretation of some technical terms
I think some jargon should be understood by people who don't know about beer making.

4. Trash can throw away items more intuitively
-> I couldn't find the trash can at first, so I thought there was no place to throw away the item.

PS
It would be nice to briefly explain the role of the tools and ingredients used, and what the ingredients taste like and smell like.

The above is a personal opinion, and I would appreciate it if you could make an official Korean version.
