I'm not a huge fan of runners, and I feel like a lot of my "issues" with this game are ones that I find prevalent with the others in the genre as well -- a lot of repetition and the levels just feel like they go on a third longer than I want them to, likely because of the long lead in / opening to each level? -- so I think that's a me-thing, not a your-game-thing.
The art is pretty cool and this seems incredibly well-polished, even if it's not for me, personally. Great work putting this together!
