About UNDEMON

UNDEMON - about the game
Play as the ghost Luna in a 90s-style 2D platformer, emerging from a lightning-struck tomb with no memories. Navigate challenging stages inside a nearby house and beyond, using a hide system to stun humans briefly, pass through obstacles, or slip past foes. Collect souls to upgrade abilities like sight range for spotting humans, flying time, attack power, and more, while hunting yellow and red keys-watch for fakes on yellow ones-to advance. Multiple modes ramp up the test: Normal offers balanced play, Original delivers slippery controls and tight visibility, and a secret mode demands soul collection for extra lives. Bosses resist quick stuns but yield to sustained attacks. This indie action game suits fans of tough, retro platforming with ghostly stealth twists.

Go on a mysterious adventure as a ghost. Various stages that stimulate a sense of challenge are waiting for the ghost Luna. If you want to feel the genre of 2D platformer in the 90s, try it!
Synopsis

Luna, a ghost, can hide slightly as a "hide"(not completely), and It can stun state the other person for a while or pass through the body. However, most people drink strange water, can see the existence of the ghost Luna.

Hiding is useless against animals.


Certain obstacles can be passed as 'hide' state.


Bump as 'hide' state at humans enemy. The human enemy in stun state for a moment and the attack is valid.


Bosses have strong energy and cannot give them a state of stun, but they pass through the body as they are. Instead, if you continue to attack, they can be stun state, so aim for that time.
