i saw her too, with lasers is the sequel to i saw her standing there, though the gameplay is somewhat different.
Unlike the first game, you do not play one of the lovers, but a mad scientist who uses lasers and holograms to guide the lovers together. They are both zombies now (the male became one at the end of the first game), so do not kill each other when they touch. And the "platforming" aspect is gone, as you do not directly control any character on screen, nor are jumps possible.
Instead, it has much more of the feeling of a switch-controlled puzzler than an action game, though there is still a bit of a performative aspect: often, you need to switch quickly from one control to another to prevent the loss of one of the zombies. The basic scheme is similar, however: on each level, guide the lovers to one another.
As with the first game, it's a nicely tuned Flash puzzler with clean, intelligent level design, and worth your while if you like puzzle games.
