Some reviewers have criticised the game's control system. "Eurogamer"'s review stated that the jump timing sometimes feels "off by a fraction of a fraction of a second" and that this can be a minor annoyance when attempting challenges which require dexterity and timing. In "IGN"'s review, Chris Roper also reported issues with the control system stating that the game's heavily physics-based gameplay "left a few corners on what should have been a razor-sharp control scheme". He goes on to say that the character acceleration and deceleration "isn't as quick as it could be" but that his biggest complaint is the way the game handles player movement between foreground, middleground and background on the 2.5D plane. He says that "there are instances where it doesn't do what you want it to do, and these points stick out like a sore thumb." This is an issue that has been raised by Media Molecule's co-founder Mark Healey who stated in an interview that "The Z movement is an incredibly hard thing for us to get right. There's times when it annoys me actually." He went on to say they would continue refining it, suggesting improvements via a future update IGN's review commented that the story mode ended "in a somewhat disappointing manner" and the story as a whole doesn't make sense.
