Gaido (The Guide) a concept for a card game I'm working on

I've finally gotten my idea for this game out of my head and onto some virtual paper. Here's the rough instructions for playing this 20 card game. Please, please let me know what you think. Thanks!

There are a total of 16 landscape cards, and 4 Journey’s End cards, represented by different birds. There are also 24 tokens.

To start the game, shuffle all 20 cards. Each player draws 3 cards to form their starting hand. Any left over cards are placed within easy reach of all players as the Draw Pile. Place all 24 tokens within easy reach as well.

This game is played over three rounds.

To start off each round, pick a starting player.

One each player’s turn, they draw one card, and then they may either play one card into one of four stacks, or discard one card into the discard pile.

There are four different landscape cards with arrows on them. These are played on the table in four stacks, one stack for each different landscape. They may be played facing any direction. Cards have numbers of arrows in this order, from Bottom (pointing down), Left, Right, Top.

1,1,1,1
2,1,1,1
3,2,2,1
4,3,3,2

Every Landscape card has arrows on it that point in four different directions. The number of arrows are the number of potential points earned by the players they point at.

If you have a Journey’s End card in your hand, you may also play this on any of the four stacks, as long as at least one landscape card is already in that stack. Journey’s End cards are always played facing towards the player who put them on a stack. (OPTION 1 - you must play a card on a stack so that more arrows are present facing you. i.e. if someone plays the 3,2,2,1 card on a stack, with the 1 facing you, you can then play the 2,1,1,1 card on it with the 2 facing you).

As soon as you play a Journey’s End card on a stack, no other Landscape cards of that type may be played on that stack and the stack is scored.

To score a stack, the player who played the Journey’s End card removes it from that stack. That player may then rotate the top card on that stack 90* left or right. Starting with the lowest number of arrows, each player takes a number of tokens equal to the number of arrows pointing at them.

That landscape may no longer be played. If a player has or draws a card of that landscape, they may keep it in their hands or they may choose as their action to discard it. You may only discard Landscape cards, and then only if that journey has come to an end.

The round ends in one of two ways. Either when all 4 of the Journey’s End cards have been played, or as soon as the last token has been taken.

Each player counts up their tokens. The player with the most tokens is the winner of that round and is declared the Gaido (guide). If there is a tie, each player is declared a Gaido.

Each time a player is declared a Gaido, they take one token from the pile and set it aside. This is their reward.

At the end of three rounds, after all Gaido have been declared and they have claimed their tokens, each player totals up their rewards. The player(s) with the highest rewards wins.
