Dungeon Crawler Animation

The first game I played was Pokemon Diamond released in 2006. Your character on the screen can move up, down, left and right. They can interact with objects, people and perform actions via your input.
If I was to make a game, I would probably make it in a similar fashion to that game with its simple controls, pixel art style and some different environments with things to do. I wanted to try create an animation loosely trying to follow my idea of the game I want to make. Even though I don't know how to make an entire games yet, I know basic javascript and I can make my own assets. Pushing these skills further would allow me to produce a functioning game and bring this animation to the next line in its evolution.
