This is definitely one of my favourites! Thought it was a bit weird at first that climbing Gun Mountain with a Gun is unconventional but then I started playing. I thought the trajectory at first was weird like "oh so my bullets shoot backwards" but when I shot my first shot I loved that you chose this method of traversal, it fits the theme very well. Graphics and audio were very solid, and the gameplay was the perfect level of difficulty. Was really cool to get the powerup too, would have liked more of that where you end up with a lot of bullets by the end. Would love to see this taken further after the jam!
