Cute game! I found the keyboard controls hard to get used to, though. It would have been nice to be able to configure the keys.
The editor is neat, but right clicking in the web version only works about 5% of the time and I couldn't find a way to quit back to the editor when testing. There is a "restart" function that does nothing, and no button to go back to editing. Not sure if those are just issues with the browser version, though.
