Assimilate from Nessylum Games is an original side-scrolling NES Homebrew influenced by the early NES arcade ports. The game is being released on an actual cart, the pre-sale for which has already started. The developer has promised that a ROM will be released precisely 6 months after the 1st cart has shipped. The ROM will lack 1 secret bonus stage and have different ending credits. Keep an eye on this project!
