Puzzled - نينتندو جيم بوي كولر

I've been stuck on level 4 for two days, but the way each puzzle twists the playfield keeps me coming back. The cartridge fits snugly in my GBC and loads clean every time.

The cartridge arrived in solid shape for its age, and the classic puzzle mechanics are surprisingly deep for a Game Boy Color title. I've been hooked on the challenge modes during my commute, and it runs smoothly despite being loose.

Finally finished all the puzzle boards on a long flight and the cartridge still saved my progress perfectly, no glitches. The "Good" condition was spot on—label’s a bit worn but it plays flawlessly on my GBC.
