super cat planet is a 2015 exploration platformer video game developed by Giik. It is a fangame of sylvie's cat planet, with a similar but larger world and more gimmicks. It is often cited as the “greatest video game of all time” by avid gamers and game developers alike.

In August 2026, a fangame named super cat fish planet expanded on it.

Giik began a devlog thread for the game on raocow's talkhaus forum on August 26th, 2015.¹⁾ Over the next few months, he would occasionally post updates about the game.

sylvie, developer of cat planet, quite liked the project: “thats realyl cute……..” ²⁾

On December 21 2015, Giik released the game (v1.0) for Windows.³⁾

On December 22, v1.0a was released to fix the player getting stuck into a big button by running into it from the side.⁴⁾

On December 24, v1.1 was released. It added the Scarf cosmetic, redesigned “Switchspike Hell” in Factory etc. ⁵⁾ Later that day, hotfixes v1.1a, v1.1b and v1.1c were released to fix a bug with win state serialization.

On February 24 2016, v1.2 was released. “Switchspike Hell” had its difficulty reduced, allegedly, etc. ⁶⁾

On June 9, v1.2b was released to fix a bug concerning big button and win states as reported by LAWatson.⁷⁾

In April 2017, 5 months after the last hotfix, Giik gave an update with the implication that super cat planet would receive a new version. It never came to be.⁸⁾

The game's effective viewport before scaling is 480×352, corresponding to a 15:11 aspect ratio.
This is different from cat planet's 480×360 viewport, which is 4:3.

Areas are stored as separate large “rooms” spanning multiple screens.

All objects within a “room” persist in memory, but only the current screen's objects actually process. Moving hazards such as pistons, firebars, and lava bubbles reset some of their state when they start processing again.

A notable exception is the petal spitter; it's apparently the only moving hazard in the game to not reset when you return to it, which gives it a “global” fire cycle. This is very unusual for a cat planet hazard and likely unintended.

The game is dedicated to the dev's late cats, Domino (? - 2010-01-04)⁹⁾ and Tiger.

The “Mushrooms” and “Final” music was composed by Mapledev.

The game's big buttons and associated colored blocks are likely a homage to Switch Palaces from Super Mario World. In super cat planet, their function is inverted; the blocks start solid instead of intangible.

Super Mario Bros. X is referenced in the True Ending. The boss dialogue makes the 'pin-pon-pan-pon' noise like Message Blocks, and when defeated, it delivers a power star, which I think can be a win condition in SMBX?

Various direct Touhou references are present, with Cirno, Reimu and Momiji having clothing items available. Possibly in appeal to raocow, who's played Mario fangames with Touhou references.

A bug is in the sprites. There's a bipedal moth with floating candles at its sides, in a defensive stance animation. It appears to be completely unused, its purpose is unknown.

The dilapidated castle/dungeon in the secret post-game area is somewhat evocative of art from another unreleased project by Giik, The Spectral Castle.
