Thanks for playing and commenting! The flames don't disappear, which makes the game constantly much harder by limiting your options. I think the best score I got was 150 (15 kills), but generally I died much sooner.

Thanks for the comment! You actually move 2 tiles horizontally, but there is a slight pause in between, which regrettably makes it seem that the controls are oversensitive. The enemies also charge 2 tiles when they are 2 tiles away.
