Hi! While browsing the #gravity tag (which has a lot of interesting games) I found this very interesting puzzle game:

https://realsharkbird.itch.io/doublegravity

It is a puzzle game where you have to put a key into a hole. But there's more. You reverse gravity and switch control between two characters, one standing on the floor and one standing on the ceiling. You also interact with objects. It connects into a simple, yet very interesting gameplay.  For example, you can move a cube with one, reverse gravity, move the cube a bit, and reverse it again. It sounds simple (probably because I can't write), but it's very fun, and challenging at the same time. I got stuck at level 2, solved it after some experimenting, but then got stuck again at level 5. If you like puzzle games you should definitely play this. It's playable in the browser, which makes it even easier to try.

Also, I think the creator of the game did a very good job considering it was made in only 48 hours! Congratulations on a great job @Sharkbird👏👏👏!
