I wish there were more than 4 worlds. I was halfway through a long car ride when I got to the end, and I was like "wow, what the fuck". ( ´ω`)
Very fun game, but also very weird. I do think the tiny sprites are better vs what they did for SML2, even if that game has much better handling. I never could get into SML2 though. ┐(ﾟ～ﾟ)┌
