I really enjoyed this
first off the game looks great, and the interactivity with the birds and scoreboard is a nice touch. Not sure if it's intentional, but the reticule in the strike zone is really distracting and the lack of visibility hurts the gameplay a little bit in my opinion. I liked the pitcher change too.
One small thing that could add to the game would be to add a decent crack of the bat sound when you hit a HR. The homeruns sound just like a foul tip.
