Sorry about the silence, almost everything failed in the past days. First, I wanted to add music to the intro. The the whole game crashed. After I fixed it, the sprites messed up. It took me a few days to repair them. But, after I was done with it, I started working on the fight system. This is how it looks today:

The fight system is still under development, the actual fight and the menu options are still missing. But it’s a start. I’m making it very flexible, so once I finished the fight system, making other fights will be done under minutes.

Note: most of the sprites you’ll see until the first release are temporary. I’ll replace them with my own, or find another one.
