I do not know whether to consider it as a finished and complete project, but I certainly managed to reach a definite and desired state. I published on the Google Play Store Hazardous Materials, it is possible that I will make some updates or fixes, but I wanted to share and leave the link if you want to try the game.
For now it is only for Android devices.
Find the game here: Google Play Store
Now I will focus on the follow-up and on how to improve and implement new functionalities, taking advantage of what I learned in this first game, with the help of Jonathan's courses on Udemy and the suggestions of this community.
Thanks to those who want to try it, leave me your comments and suggestions.
