Muscle Stack
Read full descriptionHide full description
We have a crazy game idea. There are a crazy man that work muscles in certain areas. Just his arm, just his leg, and maybe just his head. This muscle makes an exaggerated development according to the areas it works, and it overcomes the walls that it can break with these limbs. If these limbs are not developed, they can also break with another limb, but loses extra strength. Hey wait a minute we made this great game idea. All you have to do is play with pleasure. You can play this amazing game with one finger and shape the muscles building freak.
