Asterix needs to use explosive pots to break destroyable blocks; Obelix can destroy them all the time. There's also flame pots which destroy ice blocks, and mud pots which create platforms over water and lava.

Getafix, the Druid whose magic potion has kept his village from falling into Caesar's hands, has been kidnapped! Join Asterix and Obelix as they try to rescue the druid and save the village!
This arcade adventure captures the feel of the comic books very well, but the gameplay looks a bit tired.
Based on the infamous French comics, Asterix is an example of the old cliche - a platform licensed game. Asterix and his fat friend Obelix must battle through many levels to do something or other... the plot is irrelevant.
The platform action is fairly simple, but that's not necessarily a bad thing - there are loads of levels, some of which are quite large, and it's enjoyable enough to play through them. They are split into 7 rounds, consisting of 3 or so stages, which you can choose to play through with Asterix or Obelix. At the end of most rounds, you have to defeat a boss, which is no doubt another character from the world of Asterix.
The levels are quite varied, and the graphics are pretty good. There is pretty much every platform game feature you could think of - destroyable blocks, bonus pickups, water sections, ice sections, moving platforms, springs, bonus stages, and so on. The levels actually differ depending on which character you choose, so there's even more to play through - 42 levels in total.
Overall, Asterix is an accomplished if deeply unoriginal platform game - if you like this kind of thing, you'll enjoy it and if you don't, don't bother.
