HOPE YOU UNDERSTAND THIS. I was excited for POPGOES 2 when the page was out on Gamejolt. I feel sorry for the POPGOES 2 Development Team and what happened to it. A Modeler left the development team,so,the team’s finding a new modeler as we speak. So,that’s all i have to say for now. Bye! ;(

The POPGOES 2 development team will work on a project. So,HERE’S 1 QUOTE ABOUT IT: (P.S I copied it off of the 3rd Devlog)

“The members of the POPGOES 2 team will be working on a side project while development of POPGOES 2 is frozen.”
