Broken, but not unplayable for High Sierra and can only be played in windowed mode for Mojave
Granted, the store page says this game is only supported by 10.5 (Leopard) to 10.8 Mountain Lion. For High Sierra, If you can deal with strange flickering moment (only happened to me once,) the resolution staying in a 800x600 full screen window, game crashing when you try to go into windowed mode, and Mac/game cursor overlapping or adding a line of dots below them, this game is still very solid, as it's much more challenging than the other 'Dash' games.
For Mojave, the only issue is full screen is zoomed in and doesn't fill the screen properly - so the only ideal way to play is windowed, which luckily doesn't crash on Mojave!
Going by the other reviews, I'd still only recommend MacOS 10.5 - 10.8 and, as long as you're OK with some issues, 10.13 - 10.14 users.
