This would benefit from some in-game guidance (even just “Press X or Z” would go a long way). Also, I see you’re using Godot. Why not export a web build?

it could be exported to the web version, but one of the game's features is that the level is completely changeable, it can be customized to any soundtrack, and all level data is stored in a separate folder next to the executable file of the game. if you export it to the web, then at least you will lose the ability to change the level and replace the music, as a maximum, the level will not load in principle.
