Danny Phantom Ghost Sweep is an action game for kids in which you have to help Danny catch the ghosts which have escaped though the portal Mr. Fenton left open. To catch the ghosts you must use a vacuum cleaner to suck them up. In order to get to the next level you must vacuum all ghosts in a room to continue with the next one. To catch a ghost, you should never run at it or it will escape. Also, you should always activate the vacuum when then phantometer is full. If you lose power when trying to vacuum a ghost, it will attack you. You can also get some power-ups that help you recharge the vacuum, restore health, and unlock doors.
The controls are simple. You control Danny with the mouse pointer since he will always move towards it. When the pointer is close to Danny, he will sneak, and when it's further, he will run. If you click the mouse, Danny stops and activates the vacuum. You can control the direction of the vacuum with your mouse.
Unfortunately, it only includes one mode and only one difficulty level, which is actually pretty challenging for little kids.
As for graphics, they are cute but not really detailed. Moreover, sound effects and music are suitable, although the latter is a bit repetitive.
In short, Danny Phantom Ghost Sweep is a challenging game for kids that will keep them entertained for a while.
