Hack, Slash, Loot has almost no redeeming qualities. Seriously. The pixel art looks cool and retro for a couple of minutes but there is no variation on the blue tileset. What you see in the screenshots, that's it. Blue.
There is no strategy to it, you cannot avoid monsters once you've seen them and combat is random. That means you're playing a dice simulator and hoping to roll only winning numbers. There is nothing more, you can't hide, you can't change from melee to ranged fighting you have no inventory and can't heal after fights. You can't even run away because evey character moves at the exact same speed.
Gameplay-wise there are just two tyes of enemy. Those that do random damage from a distance and those that do random damage up close. Again that's it. There's no space for depth of play, roll a dice and hope.
The strange view angle sometimes makes it difficult to tell if you're standing next to something or one square away from it and also sometimes hides cupboards behind walls. A minor gripe but gvien Hack, Slash, Loot does nothing right it all adds up to a pretty terrible experience.
Lastly - and for me the most frustrating - is the 'animation'. One character moves at a time, if there are 8 serfs around you and a bunch of demons then you've got to wait for each one to do their little bobbing movement. Similarly with ranged combat, if you're firing at an archer on the other side of the map it degenerates into a very slow game of ping-poing as the arrow crosses the screeon one way and then crosses the screen the other.
Play 'Doom the Roguelike' instead. It's free and it's awesome. Hack, Slash, Loot is neither.
