I beat Earnest Evans for the Mega CD! (twice in a row lol). This is my second experience now, with this Annet + Earnest trilogy.
I love El Viento, because I think it's genuinely an amazing, wonderful action-platformer that is a ton of fun. I love Earnest Evans, because it's hilarious and weird and awkward and clunky at every step of the way. The ragdoll sprites, the "QWOP before QWOP" vibe, and the way the silly gameplay contrasts with the badass music and tone, really makes for an amusingly surreal experience. I would not seriously recommend that anyone try to play through this... but at the very least, it's fun to mess around with. (and also doable to beat if you know what you're doing)
Hopefully someday an English patch can be released for this.
