It's a good idea for a puzzle game with a good bit of content for a jam game. I enjoyed looking for the hidden orb thingies and got them all by the end! I did encounter a few bugs (like sometimes getting stuck at a ledge and needing to jump, even though it's a flat plane), but not any game breaking ones.
I had a few problems getting the key combinations to work. Especially the second one was more luck than skill for me. It was also frustrating, that I have to return to the menu, memorize the combination and then replay half of the level. But aside from that, I enjoyed it!
The music was nice and chill, but overstayed its welcome at the end a bit.
