Okay, so, i played the game once. I didn't find a save point before i died, so ill have to re-do all of it? The music was nice. Graphics were decent. It was all okay, except no lives... Thanks for making this.
The save points are the desks with phones. There are several per level. In the video, the first save point is at 1:20. YOLO difficulty has no checkpoints, but that's disabled from the start. Kid's mode will restore full health from checkpoints. I could put in a checkpoint after the starting sequence to get players ready for what checkpoints look like.
Edit: For the next update. I've added the first checkpoint to show up after the tutorial stuff.
