Gravity Circuit has been updated to Ver. 1.0.3b. You can see the patch notes for this update below.
In versions older than 1.0.3b: In the Junkyard stage (Patch Circuit), under certain circumstances it can randomly become impossible to proceed past a certain point in the level. Opening your pause menu and choosing to reload from last checkpoint can get around this issue. It may randomly happen again, requiring another checkpoint reload, but you should eventually be able to proceed normally. We sincerely apologize for this buggy behavior, and will get a patch out on affected platforms as soon as possible (presently: Nintendo Switch). You can check if your version is affected by checking if the title screen reads “Version: 1.0.3” or lower (eq. 1.0.2, or 1.0.3a). If the version is 1.0.3b or newer (eq. 1.0.4+), then you are not affected.
