Hi everybody!
Today I have been working on the tileset. I had never worked with the new Unity tile tool, so that has been a challenge for me. Thanks to Agggron I have been able to solve one of the biggest problems that I have had, I never set the pixel per unit to the sprite size and my map didn't fit. After set the correct pixel per unit value, everything fell into place.
I also have been working with the tile collision system, with this system I realized that I could create layers and I started again in the correct way. After that, I just use the Tilemap Collider 2D to automatize the collisions.
Finally, I have developed a simple free-moving system that I will have to polish later.
Right now I'm working on the character animations, so I'll be adding more information soon.
