Birdie Bubble Shooter, a simple clone of the classic Puzzle Bobble/Bust-a-move game, has just gone free. The game features over 200 levels, special bubbles to increase difficulty, and a colorblind mode. The developer boasts the game’s small 3.5MB size, so this is a good game to keep installed without taking up much of the FIre TV’s internal storage. Birdie Bubble Shooter is compatible with all Fire TV models, remotes, and controllers.
