Pilo and the Holobook
Oh my gosh, look how adorable this is! Not just the art so pretty I want to cuddle it, but an adventure game based around gathering magical stickers! There have been a few sticker-themed games of late, but most have felt too reliant on the gimmick, without the depth underneath. This, from the footage and descriptions, looks like a fundamentally strong adventure game, with the sticker element as a bonus. Downloading the demo as I type.
