Some might call this cheating, but I accidentally auto-leveled the other day. I was in the last map of the jungle where the generator is and I was kind of low on health. I saw a corner north-east of me, moved over there and then killed a wild scorpion so that his drop would block all attackers from reaching me as I recovered HP. I went away from my computer for a couple hours, and when I had come back, I realized I had gained 2 levels! There were also quite a few drops on my location. I waited a bit a saw that my corner was a spawning wild scorpions. Curious as to whether this worked or not, I came back to that spot after beating the level and left it on while I went to sleep. When I woke up this morning, I was level 21! I used a feather to get a away because it was lagging really bad. I'm sure people will be mad that I got this far without spending as much time as they did, but I had already spent hours grinding in this game and I have no regrets!
