Solo developer is building Temple of Eternal Suffering – a grim ARPG roguelite about escaping an ever-shifting dungeon

A Steam page has gone live for the game Temple of Eternal Suffering – a dark action roguelite set in a grimdark sci-fi world, built entirely by a single developer, and the level of polish is genuinely impressive.

The premise puts you in the role of a prisoner inside the Temple – no memories, no answers, just an overwhelming urge to get out. The only way forward is down. The developer recently confirmed that a mandatory dodge roll is in the game, along with a dedicated slide mechanic for one of the playable characters, the Witch.

Gameplay revolves around a hybrid skill and level-based combat system. Each run has you collecting temporary upgrades and character implants (skills) that shape your build around a specific playstyle. Dungeons blend procedurally generated and handcrafted layouts, and each guardian boss demands a thoughtful approach – though the developer notes that brute force remains a perfectly valid option.

Among the announced features:

• multiple playable characters, each with a distinct class

• a full inventory and stash system, with items transferable between characters

• visual progression – every piece of armor and every weapon changes how your character looks, with rarer and more exotic gear appearing the deeper you go

• no microtransactions

The game is set to release in 2027.
