Is it just me or is the escape button not working with HTML 5? For example in this scenario, I can't leave the code view with escape. (x works). Not sure if this was always the case, but right now, it doesn't seem to work.

In the HTML5 version, you can't leave the changing time window with a click on the escape button. (Don't ask me why.) You can exit it with a click in a corner. The displayed time doesn't fit in the image sometimes. Drawing something on images also look very different. With large objects like the ovals in the change time window, it looks better. However, the background image doesn't look very nice in the HTML5 version if you zoom in. (The circles and lines are different.)

Update code means that it will remove the imports of the java.awt.Color and .Font. You have to update the code which is underlined in red then if the code was written differently (like lowercase for colors or constructors which aren't working anymore, especially for fonts).

Isn't your wombat exactly what the ladybug is in this project? The 'addCameraFollower' method is not the method which "moves the screen", it adds the actor which will be followed. Open the 'DemoWorld' and check how it was done.
