Spritely Goblins sound nice! Do you have any gophers about? Eating your own dogfood of hoots and goblins is some evocative imagery.
What's your feeling about (cross?) compiling games to wasm? I see hoot is intended to be a generic r7rs2wasm3r. Since I'm common lispy, I was thinking of swapping out SDL2 for just parenscript 'cause I'm not sure how ECL (boehm) will play with emscripten. scheme is garbage collected to, isn't it?
