Cave Story (2004) is a famous freeware indie game notable for being made entirely by one person, Daisuke "Pixel" Amaya.

Watch as nitsuja completely destroys this difficult game with amazingly precise movement. This playthrough saves Curly and finishes with the best ending after beating Ballos.

The program used to make this run, Hourglass, was also developed by nitsuja—with the creation of this run in mind. As such, it is our first published run of a Windows game.

Downloadable encodes and the YouTube encode include commentary as soft subtitles.

Kirby Super Star is a consolidation of eight Kirby games in one. Since most of the games must be completed to reach the credits, this movie is fairly long.

The author, nitsuja, controls both players when applicable rather than letting the CPU operate the helper.

For those interested, the obsoleted movie uses only one controller. This accounts for the large time difference between the two movies.

Here you can see a revision of this game by nitsuja, 4:35.31 minutes faster the previous run by mazzeneko. The strategy used was changed radically, using Raphael instead ofDonatello and using dash moves more often.

The damage for every move was mapped out carefully by monitoring the internal values of the RAM, to be able to choose the best attack for every situation. Luck was manipulated to make some enemies appear in more convenient positions.

Unlike the other versions of this game, this version of X2: Wolverine's Revenge is a side-scrolling platformer.

Wolverine mostly uses his most powerful weapon, the adamantium claws, to strike enemies. With the claws unsheathed, he can enter an even more devastating "Rage Mode" when the player repeatedly taps a button. The game also features stealth segments in which Wolverine can sneak up on enemies and use a special stealth attack to silently and instantly take them out.

In this run, nitsuja slashes and dashes around the Weapon X Facility and manages to rid Wolverine's body of the Shiva Virus in just 14 minutes.

For a movie of a similar game, see the run of Wolverine's Rage.

An extremely short game based on the movie The Karate Kid. Had the kid been this strong in the movie, it would certainly have been... interesting.

This movie is about 10 seconds faster than the previous publication due to some surprising fighting strategies.

Dragon Fighter is a cross-over between a platformer and a shooter. It starts out in platform mode, where you can collect dragon points. When you have enough, you can transform into a powerful dragon, turning the game into a autoscrolling shooter. The game scrolls slowly in this mode, but the dragon moves fast.

By continuously switching between the two modes, it allows the player to go as fast as possible, which makes an otherwise boring game interesting.
