Its a nice start to the game, but I wish you had explored more ideas with it. As it stands this game is just the player exploring the Nether, which is a fine concept but it doesn't go anywhere. You could have used the Nether as a setting for a story or something, and include the exploration bits of the game. Also I feel like the game itself really lacks individuality since the visuals are only screenshots. Overall I'd say the game has a lot of potential if you want to keep working on it.
