Udonge in Interspecies Cave is a niche, short-form indie action platformer released on November 15, 2023, by developer UminoKyuri and publisher NupuryuSoft. It is a derivative fan work of the Touhou Project, featuring the rabbit-eared protagonist Reisen Udongein Inaba. While the game is currently available for purchase on Steam for $8.99, there is no legitimate "free download" for the full version beyond a demo that some users have used to carry over save files. Gameplay and Mechanics
The game is a basic side-scrolling "hold right" platformer where you guide Udonge through a monster-infested cavern.
Simple Controls: Movement is handled via arrow keys or WASD, with 'Z' for shooting/attacking and 'X' for jumping.
Combat: Udonge uses bullet attacks and a double jump to navigate three distinct stages. A notable exploit involves holding "Down" and spamming 'Z' to deal massive melee damage, which can defeat bosses in seconds.
Health and Failure: If Udonge's health hits zero, she becomes immobile and must charge a gauge to recover; failing to do so leads to explicit "game over" scenes. Key Review Highlights At first glance, Touhou Project and Interspecies Reviewers
