only played the tutorial so far, but I noticed a few things:
-have the next 'box' in the conversation coming on 'press space' rather than 'keyboard: space'
-Maybe your speed should slightly increase, so you can control your character better (it feels really sticky now)
-99 electrum max seems a bit low seeing the costs.
-allow multiple purchases at once (or did i miss this?), like shift+click = purchase 10
-have the monster sprites 'precise collision checking', it will cause you hitting the enemy look way smoother.
finally, I have full edition; any way i can help you with this?
