Pretty cool, polished and enjoyable experience.
I might point out that there seem to be a bug with flower bonuses, some won't seem to work (like lilies) and other don't seem to work as explained (like the water flower seems to give +4 instead of +5 even when surrounded by 4 other flowers).
I wish I could reassign bots, once you set a bot to a specific station you can't change it, I wish I could remove bots from one station and reuse them in others. For instance, I needed a lot of bots for the water extraction station, but once I placed like 6 water flowers I had a surplus in water production so I really didn't need so much bots on that station and I could have used them for another.
Also, once I click the prestige tree the game resets and clears everything... I know it's a demo and you're expecting people to wishlist it on steam, but at least I wish I could play one more run with that upgrade unlocked. Maybe let the player replay the game with at least 1 upgrade to understand how prestige works.
Still, fun experience and I'm sure the full game will be even more entertaining.
