Footprints - Solo Playthrough

About Footprints, from BoardGameGeek:

Thousands of years ago, near the end of the ice age, humans once again dwelt on fertile land. But a new challenge awaits! The ice is still melting, and that fertile land will soon be flooded. All living creatures must escape to the mountains. Your engravings and cave paintings will stand the test of time, and the skills you have honed will be passed on to your descendants. It's up to you to leave your "footprints on the ground" for the generations to come. Maneuver your clan through difficult terrain, improve your skills to advance more efficiently, gather needed resources, make cave paintings and engravings at important sites, and use your leader to inspire your clan beyond their limits, while trying to reach the cairns on the horizon before time runs out... Footprints is a competitive game with asymmetric player powers (each player has their own clan deck) and variable setup through a modular game board. Your abilities in route planning, skill improvement (engine building), and hand management will increase your chances of winning the game. The game can be played solo. -description from the designer
