GLWS but man there sure are a ton of Houdini's on the market. I was almost in this boat, but stuck with it and am glad I did. I honestly think I'm a better player for it. As an example...I finally started scoring well on Houdini I had to take a break and I played WOZ. That game seemed so easy and I beat my grand champion score easily. It honestly seemed as if the game had slowed down for me. Houdini can be a grind for sure, but once over the hump it becomes super fun.
