Let’s use IntelliJ as a game engine, just because we can
summary
Uses the IntelliJ plugin platform and Kotlin to render games inside the IDE (Java Swing UI, JCEF available but not used), reaches roughly 120 FPS on demos, and actually edits the repo: Pong renders and moves sprites, mutable variables become invaders in State Invaders and are removed from code, a dependency-maze Pac‑Man walks git history and deletes deps from build files, Sonic deletes unit tests when hit, an OSU‑style Code Hero forces paste validation, and Doom runs via a Java port; plugin ships as Code Exploder.
