I found a free game called googrid a couple of days ago and I really like it.
You can make your own creatures and release them into your own grid, which is connected up to other peoples so that the creatures can walk freely across. You can make all your own drawings for your creatures too so it’s really good if you like drawings icons, you can make them a predator, scavenger or different types of herbivore.
The only problem is that it isn’t well known so only a few people use it, with more users it would be great…
Hope you like it
