Hi there! Thanks for reaching out about the message you're seeing—“please update the game” in Metalstorm—even though you updated it just yesterday. Let’s try to get this sorted out.

To start, can you tell me how you updated the game? Did you update it through the App Store on your Mac? Also, does the message appear immediately after launching the game, or after some gameplay?

In the meantime, here are some steps to try that often resolve this kind of issue:

1. Restart Your Mac: Sometimes a fresh start helps the system recognize the latest updates properly.

2. Check for App Store Updates Manually:
- Open the App Store.
- Click on “Updates” in the sidebar.
- See if Metalstorm shows up there, and if yes, update it again.

3. Clear Cache/Data (If possible for Metalstorm on Mac): Sometimes leftover files from previous versions confuse the app. Unfortunately, some games don't provide direct options to clear cache on Mac OS, but reinstalling can help.

4. Reinstall the Game:
- Delete Metalstorm from your Applications folder.
- Re-download and install it from the App Store freshly. This ensures the latest version is fully installed and any corrupted files are replaced.

5. Confirm Network Connection: Since the app might check the latest version online, ensure your internet connection is stable and not behind restrictive firewalls or VPNs that could interfere.

6. Check for Known Issues: The Metalstorm community on Reddit has mentioned that recent updates caused some game issues where the app mistakenly asks for updates even after installing them. It might be a bug in the recent patch, and developers may release a hotfix soon1.

If after these steps the problem persists, please let me know and we can try some advanced troubleshooting, or I can help you reach out to the Metalstorm support team for more detailed help.

Are you able to try these steps and tell me what happens?
