This Is the Only Level

John Cooney's 2009 one-room platformer spends thirty stages breaking its own single layout — reversing the controls, killing the lights, handing movement to the mouse — and it is still turning up on "best Flash games" lists in 2026 for exactly that trick, even though the trick itself only works once.

Crush the Castle

A trebuchet-artillery destruction toy that Armor Games sponsored into a 2009 Flash hit and that keeps getting called "the game Angry Birds copied" — a claim that gets more complicated once you notice Crush the Castle licensed its own core idea from an earlier, smaller Flash game with the developer's blessing.

Karoshi Suicide Salaryman

A Flash puzzle-platformer where every spike, saw and falling safe is the goal instead of the hazard, built by Jesse Venbrux as the third entry in a franchise that started life as freeware on Windows a few months earlier — which means half of what looks like a fresh idea here is the series repeating its best tricks for a bigger portal audience.

Portal: The Flash Version

Two Israeli teenagers spent months translating a game they hadn't played into 2D, working only from Half-Life 2 and Orange Box trailer footage, and shipped it on Newgrounds a single day before Valve's own Portal reached shelves — then watched Valve fold 14 of its levels into an official Xbox 360 re-release two years later.

Ragdoll Cannon

A June 2008 Box2D artillery puzzler that asks you to launch floppy stickmen at a "HERE" button in as few shots as possible — polished enough to spawn three numbered sequels, a remake and a level pack, but built on a golf-style scoring idea the game itself barely uses.

Doodle God

A free browser puzzle uploaded to Newgrounds and Kongregate on 23 June 2010, twelve days after JoyBits had already put a paid twin on the iOS App Store, that went on to become one of Newgrounds' biggest hits of the year and the root of an entire multi-platform franchise — while contemporary reviewers, on the day it launched, were already naming the trial-and-error grind that the design never grew out of.
