I played through CYFTG, at the moment I am at 97% on both, I am going to have to master them at some point, youbhave definetly gotten batter at making the games less skill based and more puzzle based though because there are some levels in CYFTG that are pure skill based that took like 15 minutes to beat, while in katook all of the levels can be beaten with relatively little skill, as long as you know the tricks
