The first thing that catches your attention is the old-school feel. The player controls a Viking that must fight his way through an army of monsters. By the way that the game looks and plays, it has a style similar to Taito’s Rastan, a classic from 1987.
One thing that makes traveling through the levels more interesting is that your weapons are for more than just combat. For ranged combat, you have a spear to attack from a safe distance. However, it is also useful for navigation. If there is a wall that is too tall to jump over, throwing a powered-up spear will cause it to stick to the wall acting as a ledge. By making the weapons multifaceted, it makes for some well-designed platforming.
Of course, the combat is the real draw of the game. With the simple and tight controls, fighting is as easy as it was back in the 8-bit days. As for the fighting, the action is as varied as the environments. In one stages, you are dodging spears while sliding down slopes. In another, you are fending off mermen while riding on a raft. With the action constantly changing, it makes you want to continue progressing throughout the game.
One problem about this progressing is that it is too generous with progressing. If your character dies, you lose half your treasure and return to the latest checkpoint. Otherwise, the game does not hurt you. With unlimited lives and saved progress, it makes finishing too easy. Having either is good, but having both takes away from the old-school feeling that the game was going for. In order to make the game play like it should, the player should stick to a lives cap. Otherwise, it is possible to finish in a single day.
Even though the combat is good, the enemies, while interesting, are not as deep as the combat. The stages have its own enemies to make each location visually interesting. The problem with this is that there are only a few enemy types in each stage. In most cases, it is only a palette swap to turn the same enemy into a new one. Once you see the first enemy, expect to see it repeat constantly until reaching the boss. This might have been acceptable in the 80s and 90s, but nowadays, more variety is expected.
