I made a little video where I play with bombs and physics in my game (you find it in the video section and the name is "Playing with bombs").
I play with the idea to use elements from the game Angry Birds to get points by destroying things. With enough points you get items specialized to the chapter what you are playing at the moment.So I try a combination of a classic platformer like Mario Bros and a puzzle game like Angry Birds.
Please note that the pictures are from the pre alpha version.
What do you think about it?
