I just played your game and to be honest I think there is still much work left to do. Overall the graphics look good but the gameplay was a bit confusing. I was expecting to spend some time walking around first with a character, easily getting used to the gameplay and graphics and the story. Instead I'm jammed into a battle right away from which I didn't know what to do. I scrolled down from time to time to look at the controls description but whatever I did seemed not to make much impression on the slime. On top of that I was always out of energy. :p
But I do think the battle scene was interestingly put together. You combined some traditional rpg elements with a side-scrolling action-based battle system. Therefore I do think the battle system idea is quite original. But other than that keep up the good work. And I'm curious about version 3.
With kind regards,
