 # UltraVersenker
 
-A command-line implementation of the classic Battleship game in Java, featuring ANSI-colored console output for an enhanced user experience.
+A command‑line implementation of the classic Battleship game in Java, featuring ANSI‑colored console output for a more vivid and engaging terminal experience. When we were assigned to build a Battleship game as part of learning Java, I decided to go a bit further and explore what could be done with Java in a pure CLI environment. That led me to create a small “graphic” engine (which I’ll publish as a separate repo) built around chaxels — character‑pixels that allow fine‑grained control over foreground color, background color, z‑index layering, and even faux opacity.
+The result is that this project became not only a Battleship game, but also a demo of the chaxel engine in action — including effects like translucent clouds drifting over the sun.

+## AI usage policy:
+Because this was a learning project, all Java code was written by me without the assistance of AI/LLMs (aside from standard inline completion tools). The JavaDocs and this Markdown file were generated with the help of an LLM and then edited by me.
