Some of the mansion's secrets aren't revealed because you're not digging hard enough. Something's simply missing.
The Puppeteer seems to have decided to step in and opened a limited-time sale: Collection Merge Items, as well as food and first aid kits, are available at a discount.
📎Merge Items are those unsung heroes without which no collection would be complete. Screwdrivers, glue, tape, needles, hammers — everything that helps connect disparate finds and finally see the whole picture. Sometimes, just one piece is missing for everything to fall into place.
🍎But knowledge in this house rarely comes for free. The more you understand, the more difficult the challenges become. Therefore, stocking up on food and first aid kits is not a luxury, but a necessity: they will help you regain your strength and survive those moments when the mansion begins to weigh heavily.
If you want to stay on track, now's the time. But the Puppet Master is unlikely to let you take advantage of this opportunity for long.
