I'm making a game about exploring and surveying a foreign planet called STAR SURVEYOR. You start with a limited amount of equipment and oxygen, but as you discover more creatures and plants you can upload them to your home planet to gradually gain more abilities which will allow you to explore the planet further.
All I've really got implemented right now are the player, some creatures, some flowers, your ship, and the system for building the world.
My plan is to build a small proof of concept and release it for free in the next few weeks or months (depending on how big I decide to make it) and then if there's enough interest, make a bigger game.
