Here are some tools you can use that require no or very little coding knowlege, or are easy enough to learn that you could learn them in two months. I crapped the first version of this list out in the middle of the night when I made this jam, so if you have any other tools to suggest new developers, add them below and I'll stick them in this post!
Bitsy -- a tile-based game editor here on itch.io! Great for making games focused on exploration and small scenes. Instructions are in the app!
RPGMaker -- makes JRPG-style stuff! There's many different versions and they all cost money, but the older ones are cheaper.
