Oh my god, this game is pure evil! Just when you think you're clearing the level with your next jump, BOOM, you get spiked! Nah, kidding, had lots of fun playing it :). Very creative mechanic, especially how movement is tied to the recoil of the gun. I also liked how the game taught you one mechanic (even though it was kind of hard to figure it out) and then expanded on it during the next puzzle!
Oh, and do try this game on Chrome. I tried it on Edge and it did not do a good job displaying the viewport.
