Thanks for the answers!
I just want to point out that I don't think a reminder to use powers is enough. Right now you can lose on the next piece after using a power since it resolves it before you get the chance, which feels unfair.
I think you should have the option to use a power as a last option always. It's technically one of your available moves, so it shouldn't matter that the piece you are on doesn't fit, in my opinion.
