moi rai games followed up Monster Sanctuary with a roguelite instead of a sequel, and the monster-fusion combat is good enough to make that gamble pay off.

Aethermancer asks you to bond with, fuse, and eventually lose monsters permanently, and it bets that losing them will hurt enough to matter. moi rai games, the Italian studio behind Monster Sanctuary, could've built a straight sequel and printed money doing it. Instead they built a roguelite, and the fanbase they already had is still arguing about whether that was the right call.
The combat holds up its end of the bargain. Fusing creatures into new forms and tuning a party around an elemental Aether system gives every run a different shape, and the dynamic skill pools shifting based on your team composition mean two players running the same two starting monsters can end up nowhere near each other by hour three. Destructoid's early access review landed on an eight out of ten, and Steam's user base tracks close behind at roughly ninety-one to ninety-three percent positive.
The art is doing a lot of quiet work too, distinctive pixel-art creature designs that make even a throwaway encounter monster look like it belongs on a poster. Shifted variants, the game's answer to shiny hunting, give completionists a real reason to run the same biome a fourth time.
The roguelite structure is the sticking point, and it's a design choice, not a bug: permanent death resets your roster every run, and players who wanted Monster Sanctuary's long-term collection loop are vocal about feeling shortchanged by the swap. Runs also repeat their biomes faster than they should, and the UI's tiny ability icons get harder to read the busier a fight gets. These aren't dealbreakers, but they're the kind of friction that shows up in nearly every discussion thread about the game.
moi rai games didn't need to remake Monster Sanctuary, and the fans still pushing for a sequel prove the wound is real. The roguelite they built instead still earns its ninety-plus percent rating, one fused, permanently lost monster at a time.
