TerraGenesis

Hi Edgeworks team! I love TerraGenesis, but here are some ideas to make the terraforming challenges even better:
1. The Haumea Rotation Challenge: Please add the dwarf planet Haumea with its real oval shape. It would be an amazing challenge to try to balance its atmosphere and water oceans while dealing with its extreme 4-hour rotation speed and centrifugal force!
2. The Kuiper Belt Expansion: Please include missing dwarf planets like Eris, Makemake, and Sedna as playable worlds to terraform.
3. The Hidden Planet X: Add a secret campaign to find and terraform the mysterious Planet X in the outer edges of the solar system, where sunlight is extremely low.
4. Interactive Space Stations: Let us place visible, interactive orbital structures around our planets, like the ISS, to help manage atmospheric levels from space.
Thanks!

One of the best developed, and truly unique games out there

Great job devs, love this game. Would enjoy if you could more visually see the cities you make and the structures you build but thats a luxury overall this is a 10/10

Great game

Awesome graphics very fun and it’s very calming. Honestly, this game deserves to be the number one game. It is so fun in my opinion.

Can you add a reset button pls

Because mars has flooded with lava

Great
