Developer really knows what hes doing

I played this game many times a day on my Apple IIc back in the 80s. The idea that the developer thought to have a green monochromatic CRT display option that looks just like my old computer when I was a kid is brilliant. Its all here. The game play is exactly the same. The imagery, the physics, the sounds really are a time warp. I would pay a lot to have an app with tons of these old games on it. Lode Runner, Conan, etc.. A long list of games presented just like this. All I need are to have all the same pixels and noises.
