I'd wish there was a "Random Pac Plus" or "RandomJuniorPac."
By the way, I like your Space Invaders recreation, the two random series, and your Pac-Mania recreation.
"Don't give pearls to pig" i guess... , but there are some good options (the "rewritten series" for example that i'm a fan off) for standard/standardized mazes... so i don't know what's "not to like" here, unless disliking a random-maze for each turn! (but that is the point in your version for true variety! ʕ◔ᴥ◔ʔ ) "If you don't like pickles, don't go get some in the jar silly!" i would tell them.
An interesting idea would be to make optional "seed run" (as opposed as right now "truly random/ephemeral mazes"), like some "rogue-lite/like indie games" nowadays. It means that giving the game a "number for seed" for the randomization would always returns the exact same sequence of mazes to play with! So some players would maybe like the design/sequence of a run/mazes, and copy the seed (or try at random entering a simple seed like "008" or something at the start or in the option to "seed the run") and try to "win it"! (like my idea; a survival of only 1 life to go to map n°5/10/X or whatnot... or just beat their high-score etc...)
