Sadly, I had abandoned "One Room Dungeon" because of a lot of things that came up in non-game-development-life.
I don't have as much to do right now, so I can resume development.
I've begun building an itch.io page for my game. It's not far enough along to show off yet, but I can't wait to have a spot ready for my game.
This is my first Unity game, and the player can now run left and right, but it looks like ice skating. Googling how to get her to start and stop without the slide, but tips would be cool of you! (人 •͈ᴗ•͈)
EDIT: I increased the Player's linear drag to 1.5 and her speed to 5. This significantly reduced the sliding. Curtesy of @talecrafter.
