Oh, for sure! Don't sweat it. I've found that it is remarkably easy to completely mess up a jam entry with one or two small mistakes. I made one game too difficult which completely nuked my score and came very close on this one by setting my encounter rate just a little too high (although I suspect the use of AI, even as a joke, will likely have the same effect on my score this time around :D). But yeah, you've got a solid prototype there. Just need to pace it better and perhaps introduce some of the mechanics at a slower pace.
