Hello folks!
Today's update includes many new shiny things (well, almost).
Camera
Now the game has a camera, which moves around with the player, so the map can be bigger than the screen.
Volcanoes
Volcanoes are a thing! They erupt, burning or creating new tiles around them. They will be more likely to appear at the initial stage of the game, during terraforming. But they also last an unexpected span of time... so you never know when one might erupt again 
When a volcano becomes extinct, a mountain takes its place. GIF below (sorry, there is no visual feedback on when the volcanoes erupt, you just see the surrounding tiles changing)
Wasteland
A new tile type, which is basically a burnt grassland/forest. Results from volcanoes and wildfires (see below)
Wildfires
This will be one of the "disasters" that will appear in the game. Not sure if the player will "place it" at will, or if it appears by its own.
Fires spread according to tile types. GIF below
Eras
Right now the game has 4 main eras (stages). Each era has a different speed for the simulation, and different tile types become available of disappear.
In the first era (terragen), the player can only place water, desert/bare, volcanoes and mountains. In the 2nd era, life is introduced (not sure how), so grass/forests and everything else will appear.
More to come sooooon
