"O Fighter" is a classic pixel style arcade game.It is addictive to take your time. Though this is a single player game, but you will feel like play with multiple players. There are lots of clever(???) and dangerous enemies.
Easy to learn: one tap to control your fighter and collect stars.When you get a star, it will explode and kill enemies around it.
Hard to master: Enemies are flying slow, but your fighter is flying by an "O" track, you may break yourself. Be careful!
Have fun!
