Hey! Thanks for playing our game!
Also regarding the questions you asked
- Because the unity UI is quite hard to scale up and down and we've had some issues with it, so we tried our best to make it zoom at least a little bit
- We basically forgot that it was a thing, oops
- And regarding building with the E, I have no idea, we just thought it made sense we first thought about it, we probably should have given it another thought
I'm glad you liked our game! :)
