Funny game. I laughed at the sight of the cat and ducks holding guns. Also when I shot at the duck and all of them started shooting back, that really surprised me hahaha. I couldn't figure out the wall climbing mechanic until I read one of the comments from the game developer in reply to someone else. I knew that I had to press TAB but I didn't realize you could press A/D to move up the wall. I had been trying to jump while pressing TAB. Apart from that, I also didn't know how to change guns. I pressed E on the new gun but nothing happened. Maybe it's because I was still holding a gun? Not sure.
