Hi! The game is really fun, and I love the world design. Like other commenters pointed out, the controls and movement need to be refined and polished, but there is a lot of potential for a solid platform game.
I am a freelance video editor, and I'm currently trying to expand my trailer portfolio. Would it be ok if I tried editing a trailer for Shattered? I'd do it 100% for free, and you don't have to use the video if you don't like the end result.
