(Note: The ".rar", ".nsp", and "-eShop-" tags in your filename refer to the file format and source of the game—specifically a Nintendo Switch eShop title dumped into a ROM format. This review covers the gameplay, mechanics, and artistic merit of the game itself, regardless of how you acquired it.)
The "-NSP--eShop-" part of the filename suggests a connection to the Nintendo eShop, the digital storefront for Nintendo Switch games. NSP stands for "NSP file," which is a file format used for Nintendo Switch game cartridges and digital downloads. This implies that the file in question might be related to a Nintendo Switch version of Lovers in a Dangerous Spacetime, possibly a digital copy or a modified version of the game.
