Nice concept! :D
The game has a really nice intro and dialogue! The visual also really nice to create an ominous feeling and atmosphere into it!
The one I had an issue with is the control. It felt somewhat clunky. I'd suggest to polished it again, give the movement some impactful feedback whenever the player is doing actions such as jumping or dashing (dashing especially, I surprised it was only the sprite blinking and changing place XD), maybe try adding VFX or more impactful SFX. I'm sure it'd feel much better!
Overall, the game has a lot of potential of being a good platformer game! :D
