Copyright Infringing Nostalgia

Can you list all the characters/games in my art piece?

I was in the middle of building my game Swooping Justice, when I saw Ghostbit's Pixel Art Jam. So I thought, why not do both!? This will be a level in my game that features my mates shop, Union Heights, here in Melburn Australia. I decided to go a bit nuts for the art jam and see how many copyright infringements I can amass in a single art piece. Obviously this exact scene won't feature in my game, buy I may sneak some of characters in my game somewhere, as I build it.

Checkout my devlogs on youtube and wishlist Swooping Justice on Steam. Cheers if you did!
