well the fairy dusts now being buyable from healer has addressed the skill points regen issue. but i think it has made skill points somewhat too cheap now.
if i recall correctly back in those days we could send packages to others. one of the items would be flowers, which act as fairy dusts if im not wrong. flowers can also be gotten from the beggar. then for packages one could also send time bombs or something and the receiving person would lose energy upon opening. i thought its a really cool feature
