Replace window references with globalThis in game.js

[sonarqube-agent]

This PR was created because a team member assigned these issues to the Remediation Agent.

Fixed two SonarQube static analysis warnings (javascript:S7764) by replacing window.prompt() and window.alert() with their globalThis equivalents. Using globalThis instead of window improves code portability across different JavaScript environments, including Node.js and browser contexts.
