My favorite aspects were the characters. You used the simple triangle shapes as a good base to add personality too and I liked how distinct each one felt. Their individual theme songs really went a long way to sell their distinct identities.
I mostly allied unless I thought they would betray me and that got me through many levels, although it left me too low on points to make it all the way through, which felt fair.
The button in the top right to flip over the page took me a while to click and I had no idea it would show a helpful explanation on the back, so using a different system for that or moving that info into the "tutorial" scroll might be a good change. I thought it was some sort of "undo" button.
