I really like the concept of the game. It´s quite simple but entertaining. Skill / Shopkeeper should have an Icon above thei head - I passed by without realising them at first.
What really annoys me is the "Rest" system. It makes me now want to play whenever it is below 50%. Make the benefits from Resting different (like 75 % Atk when not rested going down to 30 % or something like that).
Logging off and wait for Rest... =/ Really don´t like that at all. Make Inn´s you can go in to rest (and pay that without gems).
4/5. Work on that "Rest System" is needed.
