Interesting game, but the movement is a bit clunky, the keys can fall off the platform you're standing on, and the keys pretty much use themselves, so I could easily win the game by throwing keys at the lock.
Also, I'm not a fan of 3D games that don't bother making visually appealing graphics. No real clue why the keys are yellow while everything else is pink.
Gave the game a 3 on the portal, pretty okay.

This could be a fun VR game too. You should make a version where you have 6 keys on a keychain and you're running from a monster... Each key has a use but you have to try them on the fly while the monster is catching up with you - like in horror movies when that happens to people. A few of the keys could be for doors, then you use one to start a car, but maybe the monster stops your car up the road and you gotta unlock another house to run in and hide or something man I dunno.

This exact idea, but with 100 keys
