Move the mouse to look around. Use the up and down arrow keys to zoom in and out. Look at the comments in the scripts to see how to do it in your own projects (look at the stage and the sprites).
A demo for making a scrolling camera that zooms in and out. Remix it, and put it into your own projects! If you have any suggestions, please tell me! Known bugs: Sometimes sprites will flicker or disappear. The bug seems to be mainly with moving sprites. The color changes cause the normal player to really slow down. See the link to the faster player in the instructions.
