Looking for flat-shaded 3D games that are being currently sold

As a person who's making flat-shaded 3D game, I am very interested in other games featuring such art with available sale figures (so either released on Steam so I can look it up on SteamSpy or sold by authors themselves with the figures available). I'm looking for newer titles that use such art style that don't have big brand (e.g. Battlezone, Geometry wars) behind them so I can eliminate variables of being a fan of the brand and nostalgia for the title and see how the game sold on its own merits. Preferably devs' first game.

Please don't tell me about games that used such style, but were released in 90s (so no Stunts/SkyRoads) as the game market was entirely different than it is today. Thank you for your help.
