I think these two deserve more love. The sidescrolling presentation and gameplay makes them stand out, but they also boast a competent combat system, interesting narratives, colorful and detailed visuals and soundtracks so memorable, I ended up whistling some of the tunes for years.
Totally going to check this out. After I finish the other great RPG freebie, Moonring.
ETA: And according to the main website, the first game apparently has a Wine patch for all of us Deck owners. Pretty cool!
