To test a game you need to create your project in a separate folder inside "Projects" folder (that is in the root folder of the editor). That is basically it. There might be an improvement upon this when I figure out a better way of running different projects.
I simply don't have necessary software to make them. A simple manual reading should be enough though. You can open it through "?" option in the main menu.
при нажатии клавиши escape в меню воспроизводится музыка. если у вас нет музыки, установленной для меню, то музыка исчезнет. нет возможности воспроизвести музыку с текущей карты, когда вы идете в меню.
this happening for me too. when i first ran it i couldn't test game, then when i imported some tiles and made a first map, it worked to test game. then i closed the editor, opened it again, and now i can't test game anymore.
but if i build game the version from the build folder works just fine.
Check if your project is in proper folder. It should be in "Projects" folder in another folder. Like "Projects/MyGame". No whitespaces, no non-latin characters.
