Display setting crash
As Rodrigo Dantas, Game Maker Studio Brasil member said, the following error message, that causes the game to crash, appeared after changing in-game display settings (resolution, colors, etc) and then rebooting the game.
I’m still working in order to resolve this issue, but there’s a workaround that can solve that.
In Windows Explorer, access %APPDATA% at the address bar, go to the upper level to find the Local directory. There, you will find a directory called brasonic2017, and there a file called settings.ini. Then delete this file to stop that error message to crash the game.
How to delete savestates?
For now, the game has only one save slot, even because it is a demo with few stages, but if you want to start over from scratch, you can do it from the outside either.
In Windows Explorer, access %APPDATA% at the address bar, go to the upper level to find the Local directory. There, you will find a directory called brasonic2017, and a file called bs1GameDemo.sav. Then you delete this file in order to delete your savestate.
For the Android version, before running the game, in your system go to Settings > Apps > BraSonic 20XX > Data Storage, and select Clear data.
