Last week, I tried and failed to rescue the Last Dinosaur Egg. We didn't even get to meet Delta Mode!
Saturday evening, I'll tackle the third of the four games: “The Hypnotic Harp”, in which Victor Vector and Yondo go to Ancient Rome and try to wrest the titular harp from the clutches of the Emperor Nero.
Let's hope for less pixel-hunting this time: https://twitch.tv/boredzo
(And if you want to see the rest of the second game, I did eventually find a YouTube playthrough that filled in what I had been missing. There's also one for the third game, so this time I'll have a walkthrough to consult if I get stuck again.)
