How to play
Your objective is to navigate the map and activate exit elevator, killing hoards of monsters in the process.
- WASD - movement
- J/L - turn left/right. Hold shift to turn quicker
- spacebar - shoot
- num 1-4 - change color mode
- x - activate elevator (arrives after 1000 moves)
By default game resolution is 64x48 "pixels", which are just a pair of ASCII symbols. That means your terminal needs to be at least 128 chars wide. You may change variables
h to your liking.
Wall rendering is done using ray casting. Monsters and projectiles are added after that as sprites. Ray casting is a simple rendering algorithm that doesn't require any 3d modeling or complex computation.
