Unstoppable Chopper

In Unstoppable Chopper, the player needs to guide a helicopter through 24 levels. The chopper automatically moves horizontally and is in danger of crashing into the numerous stationary obstacles. When pressing the one available button, the chopper moves upwards (together with the automatic movement, this leads to a diagonal direction); downward movement is initiated by leaving the button alone. The longer it moves in the same direction, the faster it moves and the longer it takes to move into the other direction again. Besides simply surviving, the player can also collect coins to increase the high-score. After each bump into the environment, a life is lost and the chopper respawns (with some invincibility time) in the middle of the screen. After all lives are gone, the game is over.
