What I've got so far for the rules (feel free to put these in the description or whatever):
- The number in the upper left is how many other cards you need to discard to play it. If there's teeth around it, you instead spend [eye points], which you gain from other cards.
- There are two "species" types, plant and animal (also denoted by the shape of the upper left, rectangle for animals and diamond for plants). You can only play one card from each species per day. Some cards, like Eelgrass and Rat, reduce costs of a species.
- There are three "enviro" types, land, sea, and sky. These have no inherent meaning, but some cards, like Red Crab, grow stronger with certain environments. (Others, like Cat, grow weaker, so pay close attention).
- The squares present at the bottom, [mind] in grey, [eye] in red, and [power] in green, are resources that are gained when you play a card and spent when a card says so. These only happen once.
- Some cards have other effects denoted by other symbols beneath them (like Eelgrass and Rat again). These are continual.
- When hovering over a card, you can see how many stars and drawn cards this card will net you at the end of each day. The total across all played cards is shown on the right. (This is pretty pertinent information, maybe put this on the top of the card?)
- There's a maximum hand size of 10. If you go over, you'll have to discard before your next turn.
