Attention Rubyists: you can write video games
summary
Claims Ruby plus Gosu is practical for 2‑D games and demonstrates it by building two working demos: Winner Winner Chicken Spinner (spin and stop win condition) and Running Hero (walking, jumping, sprite‑sheet animation, rectangular collision). Key specifics: three core methods (initialize/update/draw), assets loaded into memory, animation paced by milliseconds/100 (~10fps), gravity = 1.75, jump velocity = 30, knockback 30px, hurt timer 200ms, enemy class, scoring. Code and slides live on github.com/chamblin.
