Totally agreed that the damage could be more obvious. One thing we would have like to do if we had time was to make the damage appear in the form of damage numbers, particles that fly to the enemies when the dice resolve, or something else entirely.
There are enemy "heath bars", in a way, but it's not super obvious. The cards that the enemy sprites are on changes color from green to red as they take damage.
The dice pushing the enemy out of the way is also a problem, and something we'd like to solve, possibly by making the dice pop out with less force or wait until the attack has finished. It's particularly bad with the fireball, and it can be pretty frustrating, sorry about that :)
