Monkey Brains – This is a serious confrontation between two experimental researchers. One of them – Dr. Crype – has developed a unique technology that allows you to control the work of the mind. To embody the dream of life, you only need to experience and introduce it, after which it will remain a stone's throw to world domination. However, for any evil there is a worthy enemy. In this case, they became a scientist Simius. Realizing the scale of the upcoming disaster, he tries to interfere with the opponent with all his might.

The levels are represented in the lord of monkeys in the format of side scrolling. Simius controls the anticipation detachment, facing various tasks – pressing buttons, changing the position of levers, dodging traps and enemy soldiers. Only when fulfilling these conditions, it will be possible to get to the exit and go to the next round. It should be noted that at a certain point in time, only one animal can be controlled.

Interestingly, numerous obstacles and dangers are not able to lead to the death of the protagonist. But with the adverse development of events, the amount of health is reduced. When it disappears altogether, the game stops. To prevent this, you should regularly replenish fruit stocks.
