As simple as it is, this game is really quite silly fun. I'd love to see more of the "wait, there's more?" aspect, as occurs when the shop and dwarf show up, as in, it would be fun if all of those useless items actually turned out to be useful somehow! It's a bit slow to start, so I suspect a lot of players quit before noticing there are more mechanics than clicking a button to reveal a sentence; the sentences changing are at least a clue.
Nice use of straight HTML5 (complete with responsive layout!) to implement this one, by the way. Tons of games like this are done in Unity or whatnot for reasons unknown and have a habit of turning my laptop into a noisy fingertip warmer.
