✦ AI summary

Mysteria ~Occult Shadows~ is a hack-and-slash action game with appealing anime aesthetics and costume designs, but it suffers from significant technical problems including game-breaking bugs, janky movement, translation issues, and an apparent lack of developer support that make it difficult to recommend even at a low price point. Players who have managed to progress report some enjoyment from the combat and exploration, though most agree the game needs substantial polish and fixes to be worth playing at any cost.

Horrific mess. Full of bugs that make it impossible to progress. Appears to have been abandoned by the devs.

Overall a fun hack and slash game so far (for less than $3), however there are issues that I wish were fixed: - When you die after you start a game with no prior checkpoint, you respawn in a glitched state and cannot move, and you might have to force quit the game. - Whenever you start a game, your costume resets back to default until you re-equip it in the "Information" menu. - Some translations aren't the best; Instead of "Inventory" menu, it is "Information" menu, Instead of "Close" in the shops, it is "Disable" etc. - The jump movement is a little janky as well; It is possible to jump a little too far. The costume designs are really good, and this game has great potential, however it needs more polishing in order to be worth even close to its full asking price.

Mysteria ~Occult Shadows~ is a 3D action-adventure RPG developed and published by U-Secret Studio, an independent team that built the game around an unusual mixture of anime aesthetics, supernatural fantasy, mythology, and hack-and-slash combat. The adventure follows the Shadow of Death, a fearless cat-girl warrior exploring Sulnas, a land contaminated by a mysterious dark power. Her objective is essentially one of purification and discovery, with the journey gradually revealing secrets surrounding the Ferre civilization and the forces threatening the world. The premise is straightforward, but the darker atmosphere gives the setting more character than its colorful protagonist might initially suggest. Combat is the foundation of the experience. Battles take place in real time from a third-person perspective with a freely controlled camera, while three weapon types provide different approaches to attacking enemies. The protagonist's feline identity also influences traversal and fighting, since jumping and grappling allow her to move rapidly through environments and reposition herself during encounters. Quick-time sequences appear during certain finishing actions, giving some confro…

dont play this game. dont open this game. dont look at this game. dont buy this game. dont think about this game. its littered with bugs. i played it in 2022 when i had no money and it was like a dollar. i felt relieved when i finished it because it meant id never have to pick it up again. buy if youre masochistic and hate good games. other than that running through the manor area was slightly nice but mostly because i was listening to a podcast
