Story: You go down the well, and get to hell while shooting and slaying demons. That's it.
Gameplay: Imagine Downwell-style roguelike combined with fast and frantic shooter gameplay from old-school shooters like Doom and Quake.
Plus: Fast pace. Fairly easy to calculate damages. Resource management forces you to get a bit closer to the enemies and do many constant tactical juggling between melee and shooting.
Minus: There should have some kind of between-game difficulty settings or roguelite mode. The reward door at the bottom of the level is too tight on time, should extend by 5-10 seconds IMO. The shop NPC seems not interactable at a first glance, should add yellow glow to him to uniform the interactable color.
Interesting: Abilities. Aesthetics on old-school graphics. Very simple AI but still fun, should have flanking behavior.
Verdict: If you like retro shooter games like Doom or Quake, try this unique spin.
