their original dev signup applications described the SDK as supporting C and Lua. Pulp appears to be targetting the non-programmer gamedev scene, like Bitsy and GB Studio do currently. It looks a lot like Bitsy. They seem pretty separate.

> The SDK will be available on macOS, Windows, and Linux. There are two ways to write games: using Lua, for ease of development; or using C, for games that need extra performance. You can also use both languages in the same project. Typical SDK abilities are included: graphics, sound, inputs, text, collisions, etc. We continue to add features every day!
