About the game
Super NeatBoy is a short platformer about a very tidy character who has lost his leaves. Eight of them are scattered through a cave of fourteen connected screens, and he wants every one back. Walk off the edge of a screen to move to the next, and touch a leaf to collect it.
Apart from the leaves, anything drawn in the same hot pink as the hero is dangerous: spikes on floors and ceilings, and bats flapping in the air. Touch one and you start that screen again from where you entered it. Once all eight leaves are found, a portal opens on the first screen; step into it to finish and see your time and how many times you had to start a screen over.
John Earnest wrote it as an example program for Octojam 7, to show how a platformer can be built, and it plays as a complete game made for speedruns.
Playing it here
This is a CHIP-8 program. CHIP-8 is a small virtual machine from 1977, created for hobby computers like the COSMAC VIP, and people still write new games for it today. Super NeatBoy targets XO-CHIP, a modern extension that adds colour, more memory and better sound. It runs here in the Octo emulator.
Click Play and press A, D or Space to start. F2 saves the state of the emulator at any moment and F4 brings it back. A gamepad works too: the D-pad walks and A jumps.
Controls
| Key | Action |
|---|---|
| A / D or left / right arrows | walk left / right |
| E or Space | jump (let go before jumping again) |
| 1 | restart the whole game, clearing the time and the leaves |
| F2 / F4 | save / load the state |
A few things worth knowing
Jumps are fixed. Every jump goes to the same height, and you steer less in the air than on the ground, so start your run-up early for long gaps.
There is a moment of grace. Just after walking off a ledge you can still jump, which helps on narrow platforms.
Key 1 is a full reset. It is there for speedrunners who want a clean start, so avoid pressing it by accident halfway through.
