Definitely reminiscent of Knytt and Knytt Stories art-wise. Gameplay mechanic-wise, not so much. Too frustratingly difficult at times. The robot is a little slippery to control. Flying around, it goes to far left/right. I gave up at the second checkpoint area in the spike cave, after getting the steam jetpack, crossing the river, etc. It's the point where you have to fly and jump and wall climb before running out of steam...literally.
4.5 for the art, 3 for mechanics, 3.5 overall
