The pixel art in this game is absolutely fantastic. The story is pretty alright. The engine (for the demo) isn't very good and feels awkward and very slow at times. It also currently feels a little clunky.
I definitely recommend LOVE2D as a wonderful engine for you to use, Camila Gormaz. I also hope you look into diagonal movement and perhaps something to make the combat a bit more interesting.
Otherwise, I can't wait to play the full game!
