I think that the idea is good, and it was executed well. The games and music are good, but the art style is a bit inconsistent between (and sometimes within) the games, which can be distracting.
The ending, where after completing all the minigames you're congratulated for destroying the world is quite impactful, because even though you performed well at the minigames, what you were doing wasn't good. Many people, like myself, will think they'd somehow lost for a moment, because... we did.
Side note: Some people are confused about the log minigame. It seems to work by having you outlast the timer, and putting in a log resets the fire to full (or something similar). By putting in every log instantly, you've essentially just set it to full at the start, so you run out of fire. I don't really think this is an issue with the minigame, I think it's a pretty good way to have it work, I just think it should maybe be explained better (which is tough given the rapid-fire format)
