Hi there! I see you're having two issues with your Block Blast app: the default color setting won’t fix properly, and the "Well Done" message has changed to "Well Down." Let’s tackle these one by one.

First, about the default color issue—are you trying to reset the block colors to the original look or customize them in a specific way? Sometimes color settings get stuck due to app glitches or partial updates.

For the “Well Done” message changing to “Well Down,” that sounds like it could be a text display bug, possibly from a recent update or a corrupted resource file.

Here’s what I suggest to try fixing both problems:

1. Restart the app fully:
- Close the app completely from your recent apps menu.
- Reopen it and see if the colors and message revert to normal.

2. Clear app cache:
- Go to your Android Settings > Apps > Block Blast.
- Tap “Storage” and then “Clear Cache.”
- This can fix stuck elements without deleting your game data.

3. Check for updates:
- Visit the Google Play Store and ensure Block Blast is up to date.
- Sometimes bugs are fixed in the latest version.

4. Reset in-app settings:
- Open Block Blast.
- Look for a settings or appearance menu.
- Find and tap any option to reset the color theme to default.
- This may restore the original default colors.

5. Reinstall the app if none of the above work:
- Back up your game progress if possible (through account linking or cloud saves).
- Uninstall Block Blast.
- Reinstall from the Play Store.
- This often clears corrupted data causing display issues.

If you want, I can guide you step-by-step through clearing cache or reinstalling.

Does that sound good? Also, could you tell me if any recent updates or changes happened before these issues started? That might help narrow down the cause.

Looking forward to helping you get this fixed!
