I started on level design yesterday and came up with a few collectible items. So far you have HP pickups, coins for score and extra lives. The vase sprites are breakable and should vary in appearance in each stage. I also added in a spring object to reach higher places. Platform puzzles are going to be my next step. As you can see in the video the camera pans further down whenever you crouch. The enemies can also damage you on contact. (HP bar is visible in the top right corner along with your number of lives.)
