I'm glad you enjoyed it.
I realized partway through development that the issue with simulating an ecosystem with no boundaries is that it's not a matter of IF it will crash, its a matter of WHEN it will crash, so I put in a line of code to pull the plug if the frame rate ever drops below 0.5 fps. Definitely serves to make the experience more ephemeral for better or worse.
At first I thought about giving the player a game over if any one species went extinct, but I realized living in a world without animals is kind-of it's own punishment & I'm generally not a big fan of telling people how their supposed to have fun with a thing so I left it as more of a sandbox.
I think I will make a more polished version of this idea someday, definitely both characters need a way of dealing with the predator population for sure.
Thanks for the feed back.
