The rules of the jam are simple:
You must only use the colour red, its shades, close neighbours and greyscale, you can't use any other colour!
Also the finished product must mostly show the colour red, crimson, vermillion, etc you can't just make a full-on black & white game and call it a day! Even if greyscale itself is allowed!
Redlike comes from Rougelike which is a common misspelling for Roguelike. "Rouge" means "Red" in French.
More technical details
If you want to bend the rules a little then here's the hard red line where your colour is no longer allowed for this jam.
The red channel of all pixels can't have a value below the Blue or Green channels.
Both the Blue channel and Green channel can't have over 32 points of difference between them because obviously you can just have a value that's 255,255,0, which follows the point above, but it's no longer red, it's YELLOW and we don't want that here.
