The chiptune soundtrack, composed by CHERIS SOFT’s sole developer under the alias “Dr. Beep,” uses distorted pulse waves to simulate the whine of a lithotripsy machine. The battle theme, “Crush and Flush,” is unexpectedly catchy for a song about pulverizing mineral deposits via sonic resonance. Renalith Saga -v1.02- is not for everyone. It is slow, uncomfortable, and occasionally disgusting in its attention to bodily detail. There is a full crafting system dedicated to mixing “alkaline citrate potions.” There is a fishing mini-game where you fish for actual kidney stones in a magical urethra-river.

Developer: CHERIS SOFT Version: 1.02 (Stable/Final Patch) Genre: Medical Fantasy RPG / Dungeon Crawler Platform: PC (Windows / Linux / Legacy OS) The Write-Up In an era where most fantasy RPGs task you with slashing goblins or toppling dark lords, CHERIS SOFT dares to ask a deeply uncomfortable question: What if the final boss was a kidney stone?

But for fans of weird, mechanically dense RPGs (think Pathologic meets EarthBound with a medical degree), this is a hidden gem—or rather, a hidden stone worth passing. With version 1.02, CHERIS SOFT has polished the rough edges without removing the pain that makes the experience so memorable.

8.5 / 10 – “Hurt so good. Hydrate before playing.”
