I've only played through once so far and I may come back and add more after I've messed around with it a bit more, but I wanted to give you my initial impressions.
First off, this game is SUPER cute! The art style, the concept/gameplay, the writing, everything. It's adorable and I love it.
The puzzles were actually a little hard for me and I ended up kind of frustrated. I only succeeded for 2 out of the 4 customers. The most frustrating thing for me was that when I made a sprite for the merserker, in the description of that sprite it said that they're good helpers for gardening and such. So when the plant tamer asked for sprites to help around the garden, I immediately thought to try to recreate the sprite I'd done before. I used the exact same recipe as before but I ended up getting a boo-boo sprite.
I don't know if that was a glitch or if the recipes only work if you're making them for the right customer? It was just frustrating to do something that had made a real sprite before and have it turn out the failure sprite instead. Even if it's not the right sprite for the job if the player uses a correct recipe, I think it should still make a sprite.
But honestly that was the only problem I had with the game. I think it worked having the convos space out the ingredients (the things they all said were so cute and funny!) and the final confirmation menu was helpful. And frankly I loved all the characters so much.
Have you ever watched the Batman: The Brave and the Bold series? The merserker reminded me of the Aquaman from that series a bit. Which is a good thing.
Anyway, fantastic job! I'm glad I got to play it.
