It's a very early prototype, very barebones, super simple gameplay both in mechanics and elements. You have Wood, Stone and Food as resources and sawmills, mines and farms to automate them. That's pretty much all gameplay. Even for a prototype it didn't have much to show. Here are my thoughts:

The zen and campaign modes are basically the same, the only difference is that the campaign gives you a goal to reach and a timer to achieve it.

It's too clicky, you can't expect the player to click this much, I had to enable my autoclicker to make it playable. Maybe hover to click, and an upgrade that autoclicks as you hover.

The camera always centers on the middle of the map, if you want to see or click the land you bought on the edges you can't, it will bring you back to the center of the map. So it's pointless to grow a huge island since you'll always be working on the center tiles.

In the Zen mode, for what I've seen it gives 1 reset point per level so you'll be better off prestiging as soon as you get the button, I grew the island to a very big size with several mines, sawmills, houses, villas and so on... and it was pointless since it would still give me one reset point.

Also, to add insult to injury, the prestige tree is HUUUUUUUUGE and the reset points are given ONE every run, so you'll have to play like hundreds of runs to complete it. At the very least if this is a prototype/demo, nerf that tree and make it unlock one skill per reset point, or give at least 10-20 reset points per run, nobody will play through that huge tree one skill point at a time and you worked for nothing because nobody will get to play/enjoy those upgrades you developed. For a prototype you want people to play the whole content in less than an hour to see if they like it and give you feedback. As I said, it's easy to fix, 20 skill points per run seems more balanced.

Also, to be fair, city sims are all about seeing your city grow and managing resources, unlocking new buildings, strategically placing them, terraforming the land... to create a city and then reset it every 3 minutes over and over... I don't think it's a satisfying city building gameplay, it feels like the player wasted time building a city only to demolish it every 3 minutes.

I don't know, it really didn't click with me yet, sorry. Probably if the dev adds more content, and make the resets more meaningful it can work.

Hope it helps.
