Thank you for playing and for your feedback! I spent a lot of time on these deer :D
I knew that sooner or later the game would become boring, because for how long can you do basically 2 tasks (grabbing deers to the pen, watering and feeding them) over and over again. That's why there was a time limit (although a bit too long) so that the game ends before you get bored! I did experiment with having those tasks appear randomly and that you could take care of only one deer at once but it took away the dynamic of the game and also gets extremely difficult with tens or hundreds of deers. Seeing that you noticed it, I might experiment a bit more with slowing down the game, not having hundreds of deer but with more focus to each individual.
Once again, thank you for the feedback and thanks for playing the game! :D
