Impressive entry! I can tell that you're a fellow fan of Mini Metro like myself. One suggestion I have to potentially enhance the game is to cater to the preferences of the genre's audience. Typically, those who play these types of games are looking for a gradual increase in difficulty and a meditative experience throughout the gameplay. In this instance, I found myself feeling a bit anxious a bit too early on. Nevertheless, your entry was incredibly bold and daring, and you did an excellent job. Kudos to you!
