Glad you enjoyed it!
My rationale for putting the dialog in the corner was that I wanted it to be readable at the player's convenience without interrupting gameplay. With a bit more dev time, I would probably have had it pop up in the middle instead, but I went with something that could be quickly implemented. It's true that this makes it a bit tricky to read.
I made the special attack on the slower side so there'd be a bit of a challenge with timing it. That might not have been best. (Alternately, maybe I should have made it able to hit multiple enemies at once, rather than just one.)
