Thanks! I thought about making 4-digit ingredients instead of 3-digit ones and it felt like too much for the start of the game, but adding it as extra content would indeed be really cool. I mostly wanted to nail down the basic concept and transmit an easy, not-frustrating message of what the game's about so I didn't have many plans for additional features that would increase the difficulty curve, but I'm glad to hear that people seek a challenge in it :D. Thank you for your thoughts!
