Greed: Black Border (GBB) is a mix of Diablo style click to move player character, Kingdoms of Amalur dungeon traps, and top-down shooter combat. The mix is both interesting and frustrating.
The game is not processor heavy. Only 12-15% is required from an Intel i7-4770k CPU and 31-41% from an NVidia 770 running at 536 MHz. Backgrounds aren't as pretty, and aside from the frequent explosive canisters from earlier levels, there aren't much to interact from the environment, nor it is purposeful.
Most of the interactions (walking on different surfaces, downed enemy, broken tables, plants shot at) are paired with sound effects. The soundtrack isn't interesting, and I got tired from hearing the same (or similar) electronic music by the middle of the game.
The story is short. Enemies, gear, and environments don't have much variety. Add all that and you have what I feel like a grinding game. Controls are also an issue, specially considering how hard it is navigating traps via point and click controls. The control scheme is just inappropriate for this type of gameplay. Rogue style controls will feel better for the mazes and overall gameplay. And, too bad, rogue style control is not an option in GBB.
I did finish the game without complaining much. I did find it weird that the player can only have one passive offensive perk and one passive defensive perk active at a time. For $0.70, it's ok. Buy it. But increase the price and you'll have better games to play than Greed: Black Border.
