Thanks :)
Yeah, that is great feedback. I don't consider myself great at game design, but we've been trying to think with a friend what we could have done to make it a little bit funnier if I had more time, because indeed sometimes you're too focused on the calculator and not on the combat. Combat was mostly here to add fantasy and give meaning to why you're computing, but you're right to say that it would deserve a bigger place !
Also I know there is this weird bug, I wished I had the time to fix it :(
