Checked the live build (20024526) on this page with the same script: held Right, clicked the itch page and let go there, and keys came back empty, so the cauldron stayed put. Back in the frame, holding Left now moves it right away (585 to 165 px in a second, it didn't budge before). FASTER! pops at the 20 s mark. Both fixed. Thanks for turning it around so fast.
