Fire's Echo for Android
The gameplay is simple: Avoid the fireballs and the edges by tapping the left and right side of the screen.
The player (and sometimes the fireballs) move in a wave-like pattern. This is to avoid the game being too easy.
Each time the blue meter at the top of the screen is filled, a random modifier is added to the game. These range from making the player bigger to spawning extra fireballs.
There's no music, only a couple simple echoey sound effects. Hence the name: Fire's Echo.
There are no ads in the game. It's completely free. :)
