1.2.0-demo Patch Notes

Demo and Official Version Notice

This patch is a major update, and a hard reset will be performed for the demo.

The official version uses the Steam Inventory System and supports Steam Marketplace trading.

Therefore, the demo version will not sync with the official version, but we plan to provide participation benefits to demo players.

Border Feature

  • If you've collected multiple copies of the same sticker, you can exchange them for a border.

  • Rare borders can be exchanged for 3 stickers, Epic for 5, and Legendary for 10.

  • Once exchanged, the border can be permanently used for that specific sticker.

Mailbox Feature

  • A mailbox feature has been added where you can receive special gifts on your first login.

  • Check your mailbox when logging in and receive the initial gift pack.

Rare Sticker Special Effects

The types of special stickers included in Epic and Legendary have been changed from the previous version.

Epic and Legendary packs now include at least 1 special sticker.

  • Epic Grade: Interactive stickers that play an animation when clicked.

  • Legendary Grade: Responsive stickers that react to keyboard or mouse input.

General

  • Added border on/off setting

  • Added shadow settings with off, black, and white options

Reporting bugs on Hamster's Sticker Book GOOGLE FORM would be a great help in fixing them.

Thank you,
