Thanks for the feedback! Combat is definitely an area that needs a lot of improvement, and while my next update won't add much in terms of combat, its a high priority in future patches.
I do have a question about your answer to #4. By platform levels, do you mean areas of the game where jumping and movement are part of the challenge?
I'm asking because I'm currently working on a procedural level generation feature, and I could slip some platforming type rooms into the mix (where you might need to make some precise jumps to reach a randomized reward, or to avoid falling into spikes).
