There are no buttons to increase the Preg (Which is also not really explained how you do that, we could use some tooltips on how things work.)
The game play loop boils down to pressing the weed button every morning and then waiting untill hunger hits 3.2x and eating untill you max out the bar as much as you can.
Sometimes you shove a couple burgers in early to avoid the stomach and intestines bar, but other than that, you just repeat the same loop.
As a Hyper Preg lover, I'd love to see it also added to this, but I don't really see that fixing any of the problems I have with this.
As a Proof of Concept, this is fantastic.
As a game? It really needs some work.
Thanks for the experience!
