When I launch Run Jump Fail, it always goes on my top second monitor, and I want it to launch on the first one. Do you know how to do this? Most games launch on my first monitor.

The only workaround I have found is telling Windows to Only Display on 1 in display settings, and then go back to extend monitors after and it seems to force the game to display on 1. Until you close and re-open the game, at least.
