This is really good and very playable and I replayed quite a bit.
My main feedback is I would like to be able to see an after-action report after each round, with some sort of overview of how everyone tile performed.
Fun game! Not a pony person but I got kinda into it.
My feedback: it is sometimes kinda hard to see the current drop (at fullscreen desktop), and many times I mistake the big 'next' drop UI element as the current one and make mistakes. I'd suggest to add a second UI element with the current drop to the next drop.
