Nice demo, especially aesthetically, but I couldn't finish it because the game said I had collected 5/4 items at the ending star :/.
Also, I don't know if I'm just dumb but I struggled to figure out the controls, and I couldn't open the pause menu (I see the game has controller support, maybe you forgot to set the keybindings on keyboard for pausing?).
Overall a really nice demo, but please post a list of the key bindings
