Action Game

Control Udonge to break through the caves.

"Udonge in Interspecies Cave" is a simple action game. Move, jump, shoot! Use these actions to break through the dungeon teeming with monsters.
Defeat the three stages and their bosses.

If your health reaches zero...

You'd better recover quickly, or something unbelievable will happen...

When your health reaches 0, Udonge becomes immobile. By pressing the move keys left or right, you can charge a gauge to get back up... but if you're caught by a monster during this time...

Something unbelievable...

Unthinkable consequences! Various monsters each have their own dot motions on the map. You can still escape in this state, but if a certain event happens, it's game over...

Numerous game-over screens.

When you transition to the game-over screen, you can view large-size motions.

With each stage cleared, a gallery is unlocked, allowing you to view scenes at any time.


Will Udonge be able to safely escape this cave swarming with monsters...?
