u should change hit-exp so it is proportional to the difficulty of the monster, for instance, anacondas give the same hit-exp as garden snakes, it should be more like 10 exp per hit or a % of the kill.
another thing that would be nice is to get full hp/mp once u lvl up, it would make the game smoother and not so much grindin/inn/grindin/etc
found a bug
when 1 of ur characters gets cornered and u try to move him, game freezes and u have to reload the page, u can right click for some funny movin menus tho
