I started my code learning with javascript and simple browser games but picking up Unity was a gamechanger for me. It opened up a whole new world and also introduced me to C# which I'm enjoying a lot. Java sounds super intimidating but all the more to you for trying some things out and it sounds like you learned a lot on the way!
Your game is a lot of fun, I'm a huge fan of humor in games (if you couldn't tell by my own submission) and the mechanics feel really good. Great job and thanks for the thoughts!
