Fun to play!
Its obv still early in dev so i wont harp on things, but it would be nice to have sounds and feedback for stuff like opening doors, hitting enemies, moving jumping, etc.
The levels feel kind of off, theyre well designed and all but feel a bit too spacious / empty (rich coming from me i know). I think some more clutter and static objects here and there would help.
Also some sort of melee attack would be cool
(Theres also a folder in your demo called "Shanghai Gold_BackUpThisFolder_ButDontShipItWithYourGame", might wanna remove that lol.)
