Atomiks

# Atomiks for ArcaOS/OS2 Atomiks is a faithful remake of, and a tribute to, Atomix — a classic puzzle game where you slide atoms around a playfield to assemble a target molecule before time runs out. ## Version **1.0.4.1-2** — ArcaOS/OS2 SDL2 port ## Requirements - ArcaOS 5.x or OS/2 Warp 4.5+ - `SDL2.dll` - `SDL2_mixer.dll` ## Controls | Key | Action | |-----|--------| | Arrow keys | Move cursor | | Enter / KP 5 | Select / deselect atom | | Home / KP 7 | First level | | End / KP 1 | Last level | | Escape | Return to level select | | Alt+Enter | Toggle fullscreen | | Ctrl+X | Quit immediately | ## Running the Game Copy `atomiks.exe` and the SDL2 DLLs to the same directory, then run: ``` atomiks.exe ``` The game opens at 1024×768. Pass `--fullscreen` to start in fullscreen mode, `--nosound` to disable audio. ## Configuration User configuration (unlocked levels, high scores) is stored in: - `$XDG_CONFIG_HOME/Atomiks/config.dat` — if `XDG_CONFIG_HOME` is set - `$HOME/.config/Atomiks/config.dat` — otherwise ## Building from Source Requires GCC 9.2 (EMX/InnoTekLIBC), SDL2 and SDL2_mixer development headers, and `sdl2-config` on the build path. On the first build, `levels.h` must be generated from the level data files: ``` make -f makefile.os2 file2c.exe bin2h.cmd lev/*.dat > levels.h ``` Then build the game using the provided compile script: ``` compile ``` Or directly: ``` make -f makefile.os2 ``` ## License GNU General Public License v3.
