Plobb is a simple but enjoyable game in which you are a strange creature whose task is to destroy as many bubbles as possible in the allotted time. The bubbles are big and as you shoot at them, they start to get smaller and smaller until they finally disappear. You need to be very careful not to crash against them, or you will lose a life. You have a total of three lives. When the time is up, there will be a couple of seconds in which the screen will turn green and many small bubbles will run towards you. You need to kill them before they touch you or the game will be instantly over.
If you make the bubbles disappear from the screen while shooting at them, you will probably get a power-up like extra lives, powerful weapons, shields, among many others. The power-ups will only last a couple of seconds, so you should hurry up to get them. The game is really fast-paced and challenging, so you need to have a lot of concentration and eye-hand coordination. Sadly, the game only includes one mode and one difficulty level. Graphics are good as well as sounds, and the music is really pleasant.
In short, if you are looking for an enjoyable and challenging game to pass the time, Plobb may be a nice choice.
