Released in 2001, Pumpy is a Sokoban-like 3D puzzle game. You play as a 3D bouncing pumpkin who can push around key blocks into their respective color lock-pads in order to unlock doors and complete the levels.
It is a freeware game which comes with a good level editor, both the game and the level editor have 3 executables for Software mode, OpenGL mode and DirectX mode.
|*.3do||Possibly the models.|
|*.lev||Extension for the levels, editable with the official level editor.|
|*.pcx||All sort of textures and fonts found in the game; the interface uses .pcx graphics too.|
|*.wav||Sound files of the game, safe to replace with other sounds, allowing further modding possibilities.|
|*.mod||Probably midi files, but the extension is ".MOD" and not ".MID", this needs further investigation.|
