Thanks for your interest in showing this to your students! While I appreciate it, this game was made for a game jam (made in just a few days) and is very rough around the edges & wasn't very much intended to be educational. I encourage you to find a more polished and educationally-focused ecosystem simulator.
I do not have a downloadable build for this game however it is HTML5 so it can be played on most browsers including mobile. I recommend Chrome or Firefox.
