Wait, why am I asking instead of just making a list myself!? If you know any others (especially outside Itch.io), post them and I will expand the list.
Here are all the free pulp games currently on itch.io that explicitly allow downloading their game's Json file:
- Pulpmon (JFC it's 90% of the pokemon mechanics)
- Sprout
- Coin Germs
- Snakes (not Snake)
- Rescues (does some interesting work with multi-tile player and set player positions)
- Sunset (has objects viewable only from certain locations)
- Pulpcraft (implements individual object health well)
- The Missing Note (Sound demo)
- Pulp Projects (demos)
- Playcee's Mod (collectible card game mechanics, very sloppy documentation, real POS)
I'm going to be looking at these to see if they've already solved any problems I'm trying to solve myself; hopefully they're helpful to others.
There are also, of course, the games listed in the "how to get started" sticky on this forum:
- Neven and Dave's Game (Illusion of full-screen graphics and text display manipulation)
- Drew's Pulp Game (json in pdx) (good non-player object movement and a full 2-player pong game)
- Hotel Heartbreak (json in src.zip)
- Pulp Pong (json in pdx)
Below are additional projects that appear to have been made in pulp and include a .json file in their pdx folders. I'm not sure if it is ethical to link these, as the authors have not explicitly given permission to view their code and may have left the .json files in accidentally. If there is a forum position on this, please let me know and I will remove:
