Now this is a true RPG. I do believe this one is a winner. There are a few bugs like getting pushed out of bounds through objects I can't go though and things like that.
You could make the game harder though by adding in more than one type of enemy in an area. It's not fun to play against only one type of moster per level. If you make a second game do something about that.
Also, can you do something about the town graphics? They all look the same. Each shop is identical. Mabey you could remake them.
Another thing is that free will to go into some levels more than twice is cut off. That makes me sad. Mabey you could add a world map to go to. That would fix that.
My final thing that I didn't like was that the backgrounds of the dungeons/forests were all the same. You didn't take the least bit of time in making it so that the places have a uniqe feel. That is one thing you could work on.
