This weekends I worked really hard to finish as much as possible. First of all now there is a menu when you launch the game. Save/Load system using checkpoints. Health is displayed at the top of the screen. I've also added jumping monsters and a runner. Level is almost 10k px long :), but that's not even enough for a demo, so I'll better add some more stuff, then release demo. Thanks to everyone who follows Bit Rush!
