Main things:
1) The perspective. You can't tell where the flames will be. About half my deaths so far are because the flame landed on top of me.
2) The jumping. One time, it gets me halfway across the 'board', the next not even one flame. Regardless of how long I hold the space bar.
Minor things:
1) Levels should be put in. Different challenges. Etc.
2) Controls are a bit clunky.
Overall, good concept but nothing too special.
