The essence of the gameplay in Hellver is quite simple and is based on the passage of numerous floors of the well. You only have to go forward and overcome obstacles, kill monsters, fight mini-bosses, and survive. Nothing complicated at first glance. But in fact, everything is much more complicated than it seems. Firstly, there will be darkness around, and only the light of a flashlight with a narrow beam will help you find enemies. Secondly, you have to quickly adapt to the situation that will arise during the passage of floors. Thirdly, you have to shoot a lot.
