Rover the Dragonslayer is a very light action RPG similar to the concept of Diablo. You are Rover and you are looking to kill the last living dragons in the world. In the process, you must travel the lands, killing a huge number of monsters, and collecting souls to level up your stats and skills. Most quests, there are about twenty of them, are rather simple, requiring you to kill a certain amount of monsters or go visit someone across the map to move the main quest.
Skills can be used pressing the corresponding key; except for your basic attack, most skills require energy to be used. There are also six stats that can be leveled up a few times each, relating to Critical Chance and Damage, Health Amount and Regeneration Rate, and Energy Amount and Regeneration Rate. You can also run faster, which uses some energy, move backwards so you can face enemies while moving, and jump.
