Bubble and Squeak starts off similarly to many other platform games.
Controlling a bald child, you move through a scrolling array of ledges, avoiding contact with nasties who release coins when shot.
There are hidden areas to find as well.
Halfway through the first of the 30 levels, you meet Squeak and the full nature of the game starts.
Squeak is a blue alien, who must also be guided through the levels.
As he can’t jump as high as you, he must sometimes be instructed to wait while you flick a switch or otherwise solve the puzzle of how to guide him through.
If you stand on top of Squeak you can be launched into an extra-high jump.
Bubble Mode is an equivalent of Super Mario mode, it allows you to jump higher, run faster and shoot more lethal weaponry.
It is activated by placing a coin into a Bubblegum machine and then jumping on Squeak’s back.
In between the main platform levels there are side-view shoot ’em up sections taking place underwater completing these earns bonuses.
