Bubble Trouble
Bubble Trouble is a great retro shooter game where you control a lone character who has to destroy all the air pockets! Air pockets jump around the level and become smaller as you shoot them - every time you shoot an air pocket it splits into smaller ones - you have to represent a bean and try to shoot the air pockets without them hitting you have arrived!
You just do some specific memory breaks to complete each level and you have to try to crush all the air pockets as fast as can be expected under the circumstances. Watch out for catalysts that fall when you crush and air pockets, for example a bolt that expands the clearance height of the air pockets. This game has both single player and two player game modes so you can challenge yourself or play against loved ones!
