Probably the most successful game from the Lynx?

This one had multiple ports on other platforms. It's a fun puzzler with nice level variance throughout. Sadly, as you get to more difficult levels, you'll be spending minutes on a puzzle, only to accidently push a block you needed and you'll have to restart the whole level.

Might be one for quick save/save states on modern hardware/emulation!

Quite fun anyway, worth a look!
