You're right it does get significantly harder later.
because matches are unlimited, it seems like a better strategy to mostly focus on matching rather than wasting time focusing on the number of resources that have been made.
That being said, I think it would've been nice have a list of resources we could buy at the start of each day, or a wishlist of some sort, to keep track of the quantities of things we need. Or being off by a single resources at the end of the day.
Ideas for interaction, perhaps power-ups or ways to interact with the others' board? IE: match 4/5 puts something on the other board, randomly changes tiles on the others' board etc. It does make things a bit easier overall, but I think it'll make it more interactive and fun!
Saving a pile of unmatched food in the corner, waiting for a powerup from your partner to increase success rate or yield or something.
I liked your overall game stats.
Thanks for the game!
