AVGN Adventures wants to punish you for your hubris. All those years of playing your modern games and thinking "I'm invincible! Nothing can touch me! Bosses tremble at my might!" will be reduced down to you yelling obscenities at your screen like a twelve-year-old on Call of Duty.
A badly timed jump will end with you missing a health point (in this game's case, beer) or an instant death. It has no remorse for making you angry and for making you curse at it. Focusing your attention on avoiding a fireball might make you forget about the deathbeam or deathblock that's just after it. The game is full of the latter and makes you share in the Nerd's pain as you progress through a twisted and sinister game that's all about old-school platforming and shooting action. Its littered with curse words and references to the Nerd's videos and surroundings and fits perfectly among his mythos.
Its frustrating, but rewarding: You rarely ever want to stop playing for the feeling of wanting to beat it, of wanting to prove you're better.
It also wants to reward you for your patience. The game is filled to the brim with patterns both simple and not-so-much. Taking your time to understanding these is key to finishing each level, especially on the last where you may die a few times before reaching even the first checkpoint, which is close by. Hidden pathways, cameos, power-ups and even playable characters are your reward for exploring. Its also generous on lives; the 30 you get from the start might seem like too many, but they dwindle quickly. Also, if you're thinking of using a certain well-known old-school cheat code, you'll only end up with a good chuckle. Try it out anyway.
Its an 8-bit platformer in the vein of the Mega Man games and, much like those, you can switch between characters on the fly that have different abilities to suit the job needed. And unlike many of the game's that the Nerd has played, this one is very solid. No (unintentional) glitches and a generous checkpoint system means you won't die from a game-breaking glitch. All deaths are your own fault.
The game is definitely worth the $15 asking price for the amount of fun you can have. It was made with speed runs and twitch.tv streams in mind. It was made so you can become better at it with each playthrough.
