Hack, Slash, Loot, or "HSL", looks charming at first with it's retro-style pixel art... until you realize that the gameplay is even more primitive. It is not an understatement to say that everything in this game either comes down to little more than random chance and comparing numbers.
Combat is completely limited to clicking on an enemy until they die. That's it. No special moves, no abilities, no changing gear, nothing. Sure, depending on your weapon you either use melee, ranged or magic attacks, but unless you're fighting near a weapon drop you can't change on the fly, plus your character will usually specialize in one type so there' very little reason to change unless you get VERY skewed consumable drops (more on that later). At best you can try to bottleneck enemies in doorways or tight coriidors to fight them one by one, or run away and hope you find something useful before you get surrounded, but that barely qualifies as "strategy". And even then, you still have to hope that RNGesus is smiling down upon you.
The item system is almost as primitive. Most of the time, it feels less like you are trying to decide which weapon or piece of armor to equip, and more like you're just comparing numbers (although special damage types such as the stunning Lighting do make things a little more interesting) As for consumables, you never know if a potion or w/e will help and/or hinder you, meaning once again it's entirely up to luck rather than any sort of choice or strategy if it help you.
Oh, and there's no save system. At all.
All in all, this game had a lot of potential, but instead the gameplay is comparable to banging your head against a wall while comparing helmets and popping pills that "might" make it hurt less. What this game needed was something, ANYTHING that might have made the gameplay more complex than dice rolling: Abilities/items to use in a pinch, swapping around weapons, etc etc: anything that would make success less dependant on how lucky you are.
If you're at all thinking of picking up this title anyway, I highly recommend buying another game called One-Way Heroics instead, which in a nutshell is practically like this game with the improvements I just suggested, and at only somewhat more than half the price.
