interesting strategy, similar to board games, easy to play without instructions, but difficult to win :). I didn't win 0/4 games.
The colors are nice, but I would add danger and bonus icons on top of the cards. Colored pictograms will give you the opportunity to quickly think through and create an adventure route.
The finish card was not immediately clear. The start and finish can be made in the same color and with explicit Start Finish inscriptions or icons.
