I really love this game for its simplicity, but if I could make some suggestions on how to improve this game, it would be to have multiple save files. Also, possibly to be able to alternate between weapons & armour you've already bought. One other feature, possibly at Level 30, you could use the internet to connect and battle other players. Other then that, this game is really good! Just some Ideas to think about!
+1 if you agree with my ideas!
