Game looks good, but.
This isn't a demo, this is a preview of a mechanic seen & reseen in multiple incremental games, heavily inspired by the coinflip game, the narator talks too much he never shuts up, the game showcase like 3% of actual gameplay,
I would suggest to let the user at least finish one ending, this is ridiculous to limit the player from the basics of the game on a demo, i would even prefer no demo but a trailer than this.
Highly discourage testing.
