Thanks for the feedback! Regarding the melee attack directions, you'll be glad to know that it has already been upgraded to 8 directions and should feature in the next update. The idea to include numbers and enemy health bars is interesting, currently my vision is to keep the UI as simple as possible, but it could potentially feature as a toggle (other elements such as area previews for enemy special attacks are planned, so it wouldn't be a stretch).
There are certainly plans for more interesting abilities, her ability bar has 7 icons for a reason! More interesting interactions with fire are also planned. Glad you found the prototype enjoyable still!
