Please do not upload edited or cropped cards..Upload only original cards in PNG format, preferably checkmarked.
@Sunny Sunset I've generally found that cropped cards scan fine if they have a black border on all sides. If any of the edges are cropped too hard and are white there can be scan troubles. It's doesn't seem to matter if the image type is .jpg or .png either. On occasion I've seen gallery import problems if a card is a screenshot that isn't cropped. The screen buttons and other content seem to confuse the QR scanner sometimes. My recommendation: Always take a screenshot to show the solved seal, but always crop it and be sure to leave a black border around the card.
@retrograde there is no issue with the prgram getting "confused". It's designed to read screenshots. Please do not upload edited cards. Cropping is editing.
@Sunny Sunset I've found some screenshotted levels hard to scan, probably because of the screenshot resolution. Cropping it usually solves the problem. The easiest to scan is the "share version" of the card, or the save feature if you're using an iOS device, but the level checkmark doesn't appear on it. Anyway, the resolution in this card seems really low. As for the level, nice architecture! Are Windmills a trademark of yours? Pretty good.
@Sunny Sunset You can see it in @richardfu_ 's level, "Ramp Climbing". You set a path for B on a lower floor (by clicking on a spot) and bring the platform he is on upwards. B will think it is the same floor and use the directions needed to go to where you directed him to. He can climb on blocks, stairs, ramps, etc. with the trick, but only ones one block high (he can't climb on something when it's out of his reach).
