This is a very fun little idea. I enjoyed it quite a bit.
The puzzles and the level design all remind me of Zelda dungeons, even the art style is somewhat similar. I like how the 2 characters are quite distinct and have their own way of playing. Narratively it's quite good as well, having them try to get rid of the curse is great.
As for the gameplay itself, I found it very enjoyable - most of the time. It does get frustrating at times though when I have to wait every time to change the position a bit, which is fine I guess. Combat doesn't really feel too great a part of the game since the player can't die, the only downside being time lost. I did have a bug? at the start where ruby won't dash for the first few RMB clicks, but that was only for the first puzzle, after that it was fine.
Now the puzzles/level design like I said seemed to resemble Zelda to an extent, which I quite like so I enjoyed them as well.
The animations and art style is very cool looking as well as the sound design.
Just an overall great and fun game imo.
