I love the concept and the graphics a lot! The glow effect and using the background as an outline colors is really great.
Unfortunately it's very tough to get your bearings because there's no "you are here" marker on the map - it's way too easy to get lost, and then have too much fire to deal with because it spreads way too fast. The lag doesn't help.
Overall still a pretty good game, just quite frustrating and needs a little polish.
