 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.
 
+The name **UltraVersenker** is a nod to the German word Schiffeversenken (Battleship) and reflects my attempt to create an “ultimate” command‑line version of the game. With the help of my chaxel‑based CLI engine, the goal was to push a simple terminal Battleship far beyond the usual text‑only experience.

 ## 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.
