This was laid out well. The rain effect was great but does cause the level to take half of forever to load in the browser. Not your fault, Godot's rendring in browsers is iffy at best with some features and effects. shaders and the like really mess with it. But item and obstacle placement was good, nice use of patrolling enemy and reactive enemy. The HUD indicated a second collectable? I didn't find anything but the gold bars, so not sure if you intended to add an additional collectable item, but would be good to make sure your hud elements only reference things actively in the game to avoid confusion with players.
