Many users were having a hard time with the more difficult earlier levels, thus blocking them from seeing a majority of the game. To help with this, levels that were deemed a bit more on the challenging side have been moved to a new category in the level select screen "Challenges". Other changes: [*] Made selected card stay above the others instead of sinking back to unselected cards level [*] Added sound when adjusting the sound effect volume [*] Adjusted end of demo text sequence [*] Slight change to level 3 [*] Added translation for text for denying card pickup [*] Made "deny card pickup" info box fade out when pressing undo [*] Made deny sound play when clicking an invalid spot for rotator tokens [*] Hint button flashing will not happen if a hint has already been used on that level (and the player has not left that level) [*] The hint to press "Z" on the undo button is now clickable [*] Added game version number to title screen [*] "Buy the full game" text in the demo is now wavy
