how to play this game how to use the emulator
If you are using Windows, you can just click the download button, you get a zip archive “Pulsoids-WithWindowsEmulator”, you extract that somewhere and then you can just use any of the “LaunchGame” batch.
If you are using the itch application, there seem to be a problem where the Launch button does not find the program, so an alternative is to click on the options button at the right of launch, and “manage” -> “open folder” and like above manually run the “LaunchGame” batch file.
