Hey ^o^/) Thank you for checking it out!
You are right about the menu, I created it similar to what you see in YBF because I also love this game <3 But Blastic has always drawn characters in this stickman style, long before YBF came out. And Fuboo (the creator of YBF) is a fan of Blastic's art, so there's a chance that she was inspired by her first :D
What BC is inspired by is the concept of BTD. It's not clear yet in the first chapter, but you'll see it in other chapters later :)
