Here are the answers to questions.

Question One
Q: What was the inspiration behind your game?

A: Around 2015 I watched every game the Kansas City Royals played (I’m from Kansas City) and at times would get annoyed with the calls the Umpires were making. I made Umpire simulator(https://www.kongregate.com/games/beep2bleep/umpire-simulator https://store.steampowered.com/app/599070/Umpire_Simulator/) to see how difficult it is to make MLB speed Umpire calls. Spoiler: It’s pretty hard. I eventually made it for GearVR/Oculus Rift and tried to get it into the store. I was rejected so I ended up adding more and more modes (home run derby, catch game, shooting game, 3 inning baseball) and tried to get it in the Oculus Mobile and Desktop stores as Bleeping Baseball then Home Plate Baseball. In all cases it was rejected. I decided to just pull the plug and publish on Steam, so I published Home Plate Baseball on steam.

Question Two
Q: Tell us a little bit about your team/studio.

A: I’m the sole developer, I have a full time job, so I work on nights and weekends.

Question Three
Q: How long has the game been in development?

A: I’ve been a professional C# developer for about 15 year and have been working on games/Unity for about 10 years.

Question Four
Q: According to you what is the most interesting thing about the game?

A: On hard mode Home Plate Baseball has MLB accurate pitches (85-100 MPH) and you can try catching, hitting, and shooting full speed pitches in VR. I fudge a bit by making the collider for the bat a bit larger (about 3 times the diameter) than the bat because I found when I had a MLB accurate pitch, bat and ball it was nearly impossible to consistently hit.

Question Five
Q: What are your future plans for the game?

A: I’m looking at porting to the Pico G2/Vive Focus. At this point I don’t plan on expanding the SteamVR version.

Version 2.7:
Due to feedback, I've lowered the top of the strike zone of the Umpire Simulator a few inches.
The hard mode proved too hard for home run derby/3 inning baseball, I'm increased the power of the hits coming off of the bat. You should find it easier to get runs and home runs in Home Run Derby (Hard Mode) and 3 Inning Baseball (Hard Mode).
