“Might be the most unique and creative game I have ever played. Nothing beats the erly 2000's gaming era. One of my few childhood games I play year after year when nostalgia hits.”

— a player, Steam review · 1 hrs played“It's just a very wacky but interesting RTS of fusing 2 animals together to build your army, it's pretty fun even if some animals are better then others (avoid the Lemming & Rat, they are by far the worst units in the game)”
