Cute, simple and fun!
If I'd change anything, I'd probably take out the flame noise that continues even when you kill the flame with ice. It gets annoying pretty quickly.
Sometimes it seems there are no or almost no ice cubes spawning away from the edge which makes it impossible to move them to the middle and win a level.
Also maybe I was surprsied that the chicken is not getting hurt unless you run into the flame directly. Walking on the lava tiles seems fine ? Think it would be a better challenge if it wasn't.
