Core problem: players see "Mixed" on Steam and do not know if the negatives are about gameplay depth or launch jank. The answer: a large share of negative reviews were specifically about no key remapping on day one, camera clipping in corridors and against large bosses, crashes on final bosses, and occasional save or progression resets. Devs shipped Patch 1.0.0.1 quickly for basic keybinds and are working on camera, stability, and saves. Console players, especially on PS5, report a noticeably better time.

What the Reviews Actually Say

Negative
Launch Jank
No key remapping at launch. The number one PC complaint. Patch 1.0.0.1 added an Alpha remapping menu but it lacks multi-bind and hold or double-tap support. Camera clips and swings wildly in corridors and against large bosses. Crashes on final bosses and occasional save or progression resets. Dodge and sprint share the same button on default layouts.
Positive
The Loop and Co-op
SOUNDTRACK and gear color upgrades are the parts people consistently praise. 2-player co-op with crossplay is what a lot of positive comments highlight. The run-based mission loop works once you understand it is a roguelite, not a traditional loot RPG. Console players report fewer issues than PC.

1Do This Before Your Next Run

How a run works: pick missions at the War Table in the Sanctus Clypeus hub. A typical run is three missions, each with sections and a boss, plus a final boss if you survive. You have a life pool. Dying costs lives and can end the run. Gear you find stays for that run. You purify and keep the good stuff at the hub between runs. You cannot swap your full loadout mid-run, that is by design for a roguelite.

2Decision Points

Play now vs wait
If $20 and "good enough action with metal music and co-op" is your bar, jump in after the keybind patch. If you need tight camera, weighty combat, and polished 1.0, wait for the next patches. Devs said camera, crashes, and progression loss are high priority.
KBM vs controller
Controller avoids most of the original launch rage. Remapping exists now on PC but is still Alpha. Console players report fewer issues overall.
Solo vs co-op
Solo is fully supported and fine for many. Co-op is what a lot of positive comments highlight. The jank is easier to laugh off with a friend and you can cover each other.
PC vs console
Console, especially PS5, reports a noticeably better time than PC at launch. Most of the negative reviews are PC-specific: keybinds, crashes, camera.

Common Mistakes

Bottom line: for $20 many players who stuck with it after the first hours said the loop, co-op, and soundtrack made it worthwhile once the worst launch issues were patched. Devs are responding on X and have a support site for bug reports. More patches are expected.
