Go into the evolva directory and search for lvl files type *.lvl in Windows search. There are 12 files labeled level 1 - 12. If you open a level with notepad (i.e., level1.lvl, you may wish to back it up first) and change the Genes to:

[Genes]
Claw=100000
Flame=100000
Spike=100000
Armour=100000
Spore=100000
Stickyfoot=100000
Stealth=100000
Necrocyte=100000
Electricity=100000
Shield=100000
Mucus=100000
GeneDisruptor=100000

This will give you full "genes power." So you will have maximum power with just one animal absorbed.
