A great collection of games that harken back to the asshole-clenching games that were big in the 80s. While I am only a little bit familiar with the Nerd, I have enough knowledge to appreciate all the callbacks and references that are peppered everywhere throughout this game. Even if it's very difficult, I can confirm that this is no shitty game that sucks ass. I would go so far as to say it's an excellent collection of tough platformers that are definitely worth any nerd's time.
