Games that are implemented to be very simple by design are a bit of a struggle to review since, by their nature, there’s not likely to be much depth to them. Duel on Board would best be enjoyed in bursts with a friend, in many ways tapping into that sort of classic Pong space of a game anyone could understand and play quickly but also has enough nuance to potentially have legs. While I wouldn’t say the button scheme is ideal, your limited controls to jump, dash, shoot, or block allow for more choices in approach than you’d think tactically, and each of the game’s modes emphasize different skills as well. It may not have broad appeal but if you’ve got a competitive friend you love taking on head-to-head it may be a great diversion for a while.
