I take the slow and methodical approach today, and it works great. Every time you get eaten it sets you back a long way which makes it especially fun when I eat others. Starting in the regular green biome I make my way through the tiers until I accidentally pick an arctic evolution. This turns out to be a good choice since there aren't many things that can eat me and lots for me to eat. I quickly level into the powerful yeti and from there it's a feeding frenzy. I can disguise myself as a harmless snowball and ambush creatures worth up to 250,000 exp. This also sets them a long ways back. It took a total of one million experience to evolve into the yeti, the next stage takes five million and I just didn't have time for that today. Mope.io gameplay with my commentary as always!
