This was a really nice and chill puzzle platformer! It had a good difficulty curve, introducing things at just the right pace so that I got it without things needing to be explained. The combination of the relaxed music, the bobbing ghosts, and the sparkling stars created a really nice atmosphere.
The game has a great start, I just wish there was a bit more! The levels are just the right length to not be frustrating, so with a few more mechanics you could have enough variety to make a load more interesting levels!
I'm not entirely sure there was a benefit to having three different controls for the characters? There never seemed to be a moment where I had to control more than one at a time, so its seems like it would've been fine to have a swap button instead, and have all characters on WASD or arrow keys.
...or maybe that's just me constantly forgetting which keys I was supposed to be pressing ;)
Great stuff!
