The game is very similar to the first two titles from the Castlevania saga. In fact, the gameplay and graphics are almost identical.
As you go through the castle, you'll find upgrades for making your sword bigger, or for getting other weapons like knifes and axes – that is, practically all the same objects you can find in the Castlevania games.
Barbarians and the Necromancer's Tower is just as difficult as most other 8-bit games. Players have to be very smart to make it through the castle without letting the swarm of enemies that live there (skeletons, golems, bats, etc.) kill them.
Barbarians and the Necromancer's Tower is a very fun platform and action game that fans of the Castlevania 8-bit games in particular will enjoy. A proper homage dedicated to veterans of this genre.
