Nice arcadeish looking game, where you can find some stages similar to some certain old games that used to be on arcade machines.
The easy levels are easy to get through, and you might not even need to attack anyone, if you do it carefully.
The medium levels are tough, and you could hipothetically not attack anyone either to get through, if you plan it well, but its a lil bit of a challenge.
The medium and hard levels have though opponents/bots which are hard to get past by.
It's a fun game up to where the though opponents kick in xD

There's also multiplayer, but i havent tried it as you need friends to play with. Not sure how it works either.
