I really like the way teh exchange mechanic was implemented. There were some fights that felt way too tough and then I’d pick the right combination of abilities in the contract (usually the muse) and the fight would get a lot easier, which felt good.
I also liked that some of the choices gave the bosses new attacks. I especially liked the ‘spin’ attack for the 3rd boss with some of the contract options.
Does the dash give iframes? I wasn’t able to avoid the heart attack on the 3rd boss with the dash; I had to just run away, which made me wonder if I’d been misinterpreting the dash.
I liked the visual novel-style dialogue in-between too! I got the ‘leave’ ending, it was cool that there was a choice there. Nice job!
