A very visually clever game, with lots of brilliant shaders and art. Although, (and I mean in the most constructive way possible) J felt like an extremely awkward key to having the gunfire on. (Since the left mouse is usable why not just use that?)
Besides, that funny dialogue and I love the double jump concept with the gun. Like others, I wish there was more gameplay to fully demonstrate the mechanics!
Fantastic Job and Game On!
