Thank you to all members of this humble community for being with me. I am grateful for all comments and constructive criticism.
I wanted to let you know that I'm currently working on a continuation of Seth's adventures. I have read each of your comments here and on social media and tried to draw conclusions. In the new version, I abandoned tank control in favor of an isometric projection. I added a melee combat system and expanded the FPS mode system with several types of weapons.
