Wind & Water: Puzzle Battles - 5x resolution fullscreen test

Yuan Hao has been doing some development on his old game, Wind & Water: Puzzle Battles. Most recently, he's added 5x resolution support and asked if someone could test if it worked in fullscreen. So here we go. (I'm not good at the game, by the way. I like it, but I'm not good at it.) W&W is a puzzle game from the 2000s, originally made for the Gamepark GP32 handheld console, then ported to the Dreamcast as an unlicensed Mil-CD title. Eventually it found its way to PC. First as a paid game, then as donationware. Not quite sure it's current status, but it's definitely free to play with no microtransactions. This recording was made with OBS Studio 26.1.1 64-bit, using desktop capture to show the process. Desktop resolution is 1920x1080. Recording resolution is 1280x720 because I forgot to change that setting. First the game is run at 5x resolution in windowed mode to show that the game is working at 5x. 4x resolution fits on the desktop, 5x does not. Then the switch to fullscreen is made. The game runs, and I try a few puzzles, then Arcade | Practice, then a mission in Quest.
