Previous Platdude games have focussed on a nice simple-ish Puzzle form, but last year a simple suggestion created a whole new brand of Platdude games.
This is the third of such games, and has been re-redesigned to fit neatly into a cute little DS sized package.
The rules are simple. You have to remove 70% of the blocks from the level, which disappear simply by being stepped on.
There are also spheres that you can throw at the blocks to remove them, too.
Along the way are many enemy creatures, who will kill you with a simple tap.
Throw the spheres at those to defeat them.
A simple rinse/repeat mechanic, with a multitude of gameplay settings, and highscores for each.
