A demo for Easy Quiz has been released. The demo will only have one achievement, which you unlock for finishing the demo.
To play the demo, you just click "download demo" on Easy Quiz's store page.
If you already bought the full game, but still want to play the demo and earn its achievement, here is a step-by-step guide:
1. Go to Steam Support
2. Find "Easy Quiz"
3. "Permanently" remove Easy Quiz from your account.
4. Play the demo and earn its achievement.
5. Go back to the Steam Support page, and recover "Easy Quiz".
- Even though they say "permanently", I can assure you it is not. Let me know if you have any more questions.
