I've been messing around with Roland Yonaba's Jumper (my fork here) and getting it to play super-nicely with Corona SDK. Lua is a great language, and in my opinion, lends itself well to allowing developers to produce quality PCG in an intuitive way.
The logical next step is to see how well my Jumper modifications can scale. I've been testing with culling and enemy AI when applied to a random gameboard. I'm liking the results, and I plan on putting out a few games based on the tinkering I've been doing these past few months.
The GIF below shows off a bit of enemy AI independently moving about a grid, avoiding non-walkable structures and the main player. As a sidenote, I recently saw a note saying that Jumper doesn't optimize memory usage when calculating paths. I haven't seen a negative impact when using my Jumper implementation, but to be fair, the individual referencing the issue was generating a map that was much, much larger than anything with which I've been testing.
