Tired of constantly starting over when your health runs out? Checkpoints are the answer! Put a checkpoint down on your level, just like a platform, and give it the tag 'chk'! There are two examples given in the engine. Just as exciting, you can control time (well, kinda-sorta) just by clicking the left mouse button! Click the screen to freeze the game engine, Matrix-style, and continue when you release! Finally, LevelRead.py sees another revision to its parsing, and a few attribute tags were added to the sample data.
