The obligatory I'm in post!
I'm in but Rust is out!
Just spent an insane amount of time trying to port my Pico::Engine to Rust+WebAssembly+WebGL...
Sure it compiled for a while but sneaking around ever corner is another "cannot borrow as mutable" or reference error or a lifetime descriptor that needs to sprinkled through the entire code base... :(

Now the question is what I'm going to use... Either SDL or Pico::Engine me thinks...
