Panel de Pon (GC) / Puzzle League - 02

Normal is a bit too fast, and Hard is just nuts (as one should expect). The GBA version is still my favorite version.
The chain counter turns into a question mark after 14. Why? That's so fucking retarded. They already dropped that in PPL. Why did they bring it back? Well, at least they fixed it for the GBA version that came out a couple of years later.
