So this is what a randomized playfield looks like:

I think that I’ll need to stick to pre-made playfields unless I can come up with a really clever way to make the game randomize cave-looking areas with enough space to maneuver so its’ not completely unfair like this.

The upside of having the stages pre-planned is that they’ll generally be of higher quality because they were intentionally designed to be a certain way. The downside, of course, is that they come to an end, and so does the game.
