OK. I have done simple AI for Edwin, finished the potion system... Now I have to rebalance the HP drops (potions are useless with current drops), remove all refill stations, and eventually rebalance money. One question: with 20$ for one enemy (more for bosses) and 1$ for each heart collected, is 500$ a good price for a potion? Also, maximum money you can carry with you is 4000$ right now.
