My impressions after more than a quarter of a century:
Pros
- * Responsive
* Smooth animation of falling pieces
* Fast loading
* Patterns on blocks rotate with blocks
* Key selection
* No sound
- * No preview of next piece
* No pause
* Boring scoring
* Acceleration is too slow
* Clearance bonus causes sudden acceleration
* Playing area too tall
* American spelling of preferred
* No sound
