As a continuation of my post about getting free exp from the critical training game, I also just turned in 300 some clovers in one turn, if you just hold the left mouse button, don't click it, it will allow you to just continuously feed the mushroom in the museum (THANK YOU for including this feature, and my mouse button thanks you too :) ) after about 100 clovers being continuously fed, the mushrooms mind is blown and it's head explodes!
Little cheat I discovered - you can power level AFK at the CRITICAL training game. you will get exp every time the scarecrow flinches, so your level will just continue to raise. Figured this out when I minimized the window to look up something, came back and had gained several levels. Let it run for a couple hours while I has supper, came back and had gained over 50 levels and a 150 some clovers.
Wow, okay devs, I killed foxzilla, it jumped me to the next section, but the screen did not scroll with my guys, so they walked off and promptly died. I don't know what killed them, but then it took me to the exp screen, it gave me my exp fish... then continued giving them to to into the negative numbers, I was still gaining exp. It went to -42, then I refreshed the browser page. A few issues there for you to look at, lol
