Very fun game ^^ Could use some fine tuning near the end, but I really enjoyed the variety of upgrades and the sounds, petting mechanic, the conveyors etc. were really nice touches. The game feels very interactive. Other than some more upgrades near the end (if you plan on keeping the 1b retire goal), I have a couple more comments for polish ^^
1. Maybe have a clear definition of our goal near the start of the game, not a big thing, but it helps understand what the player is doing.
2. There should be a bit more of a clear indicator, "feed your chickens or they perish". It was funny when it accidentally happened, and I felt bad for the little guys after my moments of confusion. Again, not huge, just mildly helpful for the overall experience.
3. If you plan on a longer game, some use for our big magnet in the late game might be fun. Probably should be a "do this for extra profits!" thing rather than something you have to do constantly, because part of the incremental experience IS automating. I just enjoy having the option to use the starting mechanics sometimes.
Overall, you did great! ^^ The end screen was very fun as well.
