This is a super fun and cool concept to connect the puzzle game with a farm type area the player can build in. I thought the graphics looked great and all the animals stood out well for the puzzle part. The core gameplay of matching up the animals felt great with making long chains. Good idea to start by building off the puzzle example, that's a great way to get started!
I was able to get most of the combinations of matches after looking at the spoilers but took a little before I really understood how all that worked. It could help to somehow visually show what is happening and maybe have a special sound effect for some of these combos. Like when a player makes a carrot, how do they know that? This could even just display on the bottom of the screen to start with.
With a very open game like this it can help to have an endgame so players have at least an overall goal, like maybe there are a list of things you need in your town for it to be complete. Also, I think even just in it's current state, it could really benefit from saving the town and puzzle to local storage. This way players can leave and come back to it like you would expect for an idle type game. Overall, great work, I really enjoyed playing!
