Greed: The Mad Sci­en­tist was orig­i­nal­ly released Dec 17, 2018 by Urchin Games and then re-released for more mod­ern con­soles in 2024. It is the first game in the series. This walk­through was start­ed because I ran into a weird glitch and could not find the answers either in-game or online. In the end, though it did allow me to pro­ceed, I restart­ed the game and was able to enjoy it the way it was meant to be played. Although the graph­ics seem like it’s some­thing from the ear­ly 2000’s, the game­play is fine and smooth.
