This is one tough as nails puzzle platformer. The idea is really solid, using a gun in different ways to launch yourself into the air. Simply launching one straight down so I could bounce up and up was enough to get me through a lot of the challenges, but not the curved pillars.
The objectives and tricks to get around were never really articulated in the game. I had a ton of fun playing around, but I think more people will be turned off by the difficulty without a little bit of hand holding through a tutorial. Either way, pretty fun!
