Hi, your game is good, but maybe too simple, if you want to make something else to the game, or a sequel, try making enemies that you have to fight in order to advance through the maze. Don't worry if you don't want to make that, your game is very addictive right now haha. 

It’s a nice idea and I do have exactly such game in the works, but it’s stalled for months. You can see a proof of concept here: https://godai78.itch.io/pocket-dungeon
