Hello everyone, we've recently received multiple reports that the game only comes with a black screen when it's run in full-screen. We assume that this bug is related to recent Windows 10 updates, and we also found that several other GameMaker: Studio based games are experiencing similar problems. To solve this issue, you should run the game in compatibility mode. Please follow the steps below. [list][*][b]1.[/b] Navigate to the game folder. [list][*][b]1-1.[/b] Right-click the game(SPLIT BULLET) in your Steam library, and select "Properties". [*][b]1-2.[/b] Click "Local Files" tab and press "Browse Local Files..." button to open folder.[/list] [*][b]2.[/b] Right-click "SPLIT_BULLET.exe" and select "Properties(R)". [*][b]3.[/b] Move to "Compatibility" tab, and enable "Run this program in compatibility mode for:" checkbox under the "Compatibility Mode" section. (Windows 8 will be set by default, so you won't have to touch the drop-down list.)[/list] Since this problem is OS/engine-related, it seems that there's no fundamental solution right now. Following all of the steps above will fix the problem, for now. We apologize for any inconvenience. Thank you.
