It's a cool game, but a bit difficult, although I thought so before, but now it seems to play normally)). In general, you play as three Vikings, each of whom has unique abilities and is needed in specific situations.
I don't know their names, so we'll distinguish them by their appearance):
1) The redhead Viking or the Runner (apparently the leader of the gang). He can jump and run, and also break walls by running into them.
2) The beardless Viking or the Combat Viking. He has a sword and a bow, which he uses to kill enemies.
3) The Viking with a helmet over his eyes or the Defender. This Viking carries a shield, which he can use to protect himself from all dangers (whether it's an evil mob standing close and trying to attack, or a laser gun shooting), in general, no one can get past him; they just bump into him and stand there. He can also raise his shield so that the redhead can use it as a platform to jump onto various heights. And another use for the shield is to soften falls; it acts like a parachute or an open umbrella.
