Don't know if anyone posted this yet, but THE CRITICAL TRAINING IS EXPLOITABLE. You can go AFK and come back hours later having won a decent amount of critical, health, and levels. This gets absurd when you get to level 70, since turbo is unlocked and you get 26, 27, 28x combos doing absolutely nothing. Peace.
to beat the alligator lelvel, recycle your chloroplasts, increase your membranes a couple of times and load up on lysossomes, slicer enzymes and the shield thingies... also, remember to keep moving so you can get some glucose and aminoacids...
I suppose it's impossible, or waaaaay to slow, to get the last badge without 5h of play, wich makes the game simply average.
I did have a good time in the first two and a half hours, tough.
