The Ultimate Block map features lots of fun puzzles as well as a complete overhaul of Minecraft’s visual elements. The visuals are changed by an attached resource pack rather than command blocks or other mods though, so you don’t need to worry about compatibility issues with The Ultimate Block and any mods you might have installed already. The map will render and work fine, regardless of what mods you might be using. As for the map content, it’s nothing out of the ordinary. There are levers, buttons, pressure plates, and similar puzzles, as well as a handful of short parkour courses to clear.
All told, it should only take a few hours to play through and beat The Ultimate Block, so it’s perfect for killing an afternoon if you’re sitting around with nothing else to do. There are a couple of points where poor play could get you stuck in a level, but most of these points also come with reset buttons to start the level over if that happens. Still, it seems like The Ultimate Block was either a little rushed or not tested enough by the author before being published. You might get stuck while playing, so if that’s going to bother you, maybe try a different map.
