Nice little game! The icons where immediately recognizable as hot or cold, and the increasing speed helps making the game challenging. I only felt that maybe there could be more mechanics, like maybe having ammo to shoot some of the obstacles away, since the game reaches a point where you can do nothing but get hit since the screen is very small.
But overall the game is very simple, well done and a fun little experience, congrats!
Also my score was 106 :)
