This is a good paper that uses the Ecology of Games Framework (EGF) to study participation and power asymmetries in the water governance forums.  It is interesting to see more applications of the EGF in the global South, particularly in South American countries. The manuscript includes a pertinent review of the literature, an appropriate discussion of the methods used and a very clear and well-rounded discussion or results. However, the manuscript needs some clarifications to strengthen the main arguments; therefore, my recommendation to revise and resubmit. I offer a few suggestions on how to improve specific sections. I also present some questions that arose during my review of the paper that I consider worth discussing in the final version. Finally, I offer some suggestions to fix minor problems with the format.
