Short and simple, but very stylish. Reminds me a lot of Kid Icarus, with the wrapping and one-way scrolling. The art style is appealing and well-executed. The movement is smooth, and I like the level design; the turrets blend in really well with the scenery in a good way and are easy to overlook, requiring the player to really pay attention, and there's at least one really nice puzzle requiring the wrapping mechanic. I'd be interested to see an expanded version with more content and ideas, but what's here already is really good. I also think using horizontal mirroring (aka vertical arrangement) would be an improvement, since it would allow glitch-free scrolling.
