Yeah! I really loved the topic of this jam, I kind of hope there'll be another similar one again at some point! I also hope I can play a few of the other entries myself before the rating period ends.
If you aren't familiar with Dark Souls (which this game is a terrible spoof of) I imagine everything must have felt much more random than it already is anyway. If you can spare 5 minutes I suggest watching the following video (is there no way I can link this without embedding? It's so huge)
I must admit I haven't done that much with MV yet, but from my limited experience it is mostly the same as VX Ace (Although I only made one game with VX Ace, so not super experienced there either). I think the main exception is that scripting works a lot different because it doesn't use that Ruby (was that the name?) scripting language anymore, to my knowledge. But the core things regarding events and databases, tilesets, etc. all look really similar!
