Example does not work

[eterps]

Sorry if I'm missing the obvious: I suppose I need to cargo run --example simple.

Which results in:

warning: unused variable: `font`
  --> examples/simple.rs:10:9
   |
10 |     let font = Font::load("assets/font.ttf");
   |         ^^^^ help: consider using `_font` instead
   |
   = note: #[warn(unused_variables)] on by default

warning: variable does not need to be mutable
 --> examples/simple.rs:8:9
  |
8 |     let mut x = 10.0;
  |         ----^
  |         |
  |         help: remove this `mut`
  |
  = note: #[warn(unused_mut)] on by default

After fixing the warnings you get:

I tried again specifying the full path to the sprite, but that resulted in the same error as above.
