I wake up, and go on hacker news to see what people are doing. With my coffee in hand I play your game, fingers still cold. I loved it. Reminds me of when I was younger. Fun names to all the monsters.
Also, even other lightweight games like this that I've tried before sometimes stutter, or take forever to load in, this is amazing.
If I can ask what kind of tech stack is used to make something this smooth, and run on the web?
