The spooky theme and music works great, there are just a few things I noticed that might help improve the experience for new players.
No guidance at the start, which made it difficult to understand what the player was supposed to do. A short splash screen or message at the beginning explaining that the goal is to avoid the ghosts and survive would make things much clearer.
No damage feedback, when the player gets hit by a ghost, there’s no visual or sound effect, which makes it hard to realize you’ve taken damage unless you are constantly watching your health bar. Some feedback (like a screen flash or a sound) would help a lot.
Touch controls, the on-screen buttons felt a bit too close together and small, making them difficult to press comfortably. Spacing them out and increasing their size slightly would help.
Joystick control, it works well, but it's also quite small. For example, after releasing it, you have to tap the same small spot again to move the player, which slows things down. A slightly larger joystick area would allow smoother movement.
As for the art and concept, everything fits the spooky setting nicely, but just a small suggestion, the light coming from the window feels a bit like daylight. If it instead looked like moonlight or a night scene, it could make the atmosphere feel even more eerie and intense.
Also, since the player character appears to be a ghost, it feels a bit strange to be avoiding other ghosts. If the main character were a human who wandered into a haunted mansion, it could add a stronger narrative and make the spooky encounters more meaningful.
Overall, it’s a great start and has a lot of potential.
