A short and challenging game about fragility and dodging literally everything.
I can't give much to the story of this game as you are literally sentient bubble, but that's not what it's about. The game play and art style is where this game shines. Just as Ericho said below, the attention to detail is amazing, things like worms, bodies, lanterns, pebbles, and droplets of water, really set this apart from other games in 2002.
The game is simple, don't touch anything, and that simplicity makes it all the better. Through the 13 levels you learn to adjust your speed to dodge even the smallest of things. Additional challenges, such as air currents and moving objects were a nice touch. The time trial at the bottom that adds to your score gives the game a little bit more replay value as well.
In short, simple, challenging, and fun. Good job Struma.
