It's a pixel art comic (season 1 was a sprite comic). You don't need to read season 1 to understand season 2 (any references to season 1 are done as if you never read it). However, since season 1 and season 2 are posted in the same comic, you could read season 1 first if you want to (though season 2 is of higher quality anyway). Now I'll just shut up and post the URL:
