This was fun! Some of the jumps were a bit unforgiving (the level 1 key in the spike tunnel being tricky for me), and there were a lot of quick button taps when doing the swaps, but that's not necessarily bad. I was hoping for some quality-of-life stuff when I first played, like holding jump as the witch auto-hovering at max height and not having to release and press again, but I got used to it.
I had more fun with the parts where you had to use some of your unique mechanics, the swap idea and different characters is very fun. Resource management can be tricky to get right but I think the checkpoints were well spaced, but it made me scared to use the witch's attack. Would have been cool to have some switches that could be hit by the projectile for instance, which could then have led into more timing puzzles?
Enjoyed the music and art too!
