This game comes in two different formats but, since both of them are one-pagers, I'm afraid there's not really a way I can make a "Demo" version of a game that only has 2 pages.
You can lookup Lasers & Feelings as well as some of its hacks (there's a website that has a huge collection of them, almost all being free) to have an idea of what these games look like. The PUSH game page actually does have a free version you can download - it has the 2-page Canva template I used to make my game, so that'll give you an idea of what it will look like as well.
