Net High's gameplay is noted to be similar to the Ace Attorney series of games in regards to its puzzle-solving, though instead of solving cases in a courtroom, the goal is to reveal the identity of people on the internet. According to an interview with XSeed, the reason the game was not localized was because most of the puzzles were based on Japanese puns and wordplay using written kanji characters that often have multiple meanings, made more difficult by the fact that a lot of the text was displayed from top to bottom rather than from left to right.
