I’ve known of Ludum Dare but this is the first time I’m participating in the event. I’m really looking forward to it.
I’m planning on writing the game in Ruby using the Gosu library. I have a small personal library called Okami that encapsulates Gosu in a ruby-ish fashion, but doesn’t differ all too much from Gosu. It’s available on https://github.com/Aerotune/Okami and https://rubygems.org/gems/okami
I will probably also make use of some of the awesome gems for gosu like chipmunk, ashton, texplay for visuals and releasy for releasing the game.
