Nightmare Boy is a fun experience for a few hours, and a lot of the glaring design choices around the gameplay can be overlooked or ignored for the most part. While Billy may feel heavy to control, he does almost always make it to the platforms, while the fighting systems are quite basic, but it allows for the focus to be on the exploration side of things instead. In terms of the aesthetic of the various areas as well, The Vanir Project has done a terrific job in stylising the different sections and making every area feel fresh and new, without getting bogged down with repetitive enemies. While the platforming-based abilities work well, the combat-based abilities leave a lot to be desired, as they lack any flexibility within the combat arena, and even when those abilities are fired off, they do little damage to be worth its while compared to the base attacks. While this can be replayed, there's very little incentive to do so.
