Hi there! I understand you're having trouble progressing to other worlds or collecting resources in Mergest Kingdom. That definitely sounds like an important part of the game to get through.

To help you best, could you tell me a bit more? For example:
- Are you stuck trying to unlock the next world, or is the game not letting you enter at all?
- Are you unable to collect resources within a world you've already accessed?
- Have you tried any steps so far like restarting the app or checking for updates?
- And just to confirm, are you playing on a Windows device with WebKit browser as you mentioned?

Once I have a bit more detail, I can guide you step-by-step. But here are some initial things to try:

1. Check for Game Updates: Sometimes the game won’t let you advance or collect resources if you’re not using the latest version. Make sure your Mergest Kingdom app is fully up to date.

2. Restart the App & Device: Close the app fully, and maybe restart your Windows device to clear any temporary glitches.

3. Verify Your Internet Connection: Since unlocking worlds and collecting resources may require server communication, ensure your network connection is stable.

4. Review Your Level or Quest Requirements: In Mergest Kingdom, advancing to new worlds often requires reaching certain levels or completing specific merges/tasks. Check if the game is waiting for you to finish any prerequisite actions.

5. Clear Cache (if possible): If there’s a cache related to the app on Windows or your browser, clearing it might help remove corruption that blocks progress.

If these don’t fix it, let me know what you’ve tried and what exactly happens when you try to advance or collect. We can then dive into more detailed troubleshooting together.

Are you ready to give these a shot and tell me what happens?
