+  <desc>Mice! is a strategic single‑player game where you place bombs and mines to exterminate rats before they reproduce out of control. It features randomly generated mazes (DFS), sprite-based graphics, and sound effects. Inspired by the classic Rats! for Windows 95, this version is written in Python and uses a lightweight custom engine with SDL‑style rendering.</desc>
