Isometric Sokoban

Isometric Sokoban arrived on June 14, 2026, and it is a landmark release for the Commodore 64 homebrew community. Today we are playing it with full gameplay and commentary, and if you are new to the channel, welcome. This is exactly what we focus on.

This is the first-ever isometric Sokoban game created for the Commodore 64. It was programmed entirely in 6502 assembler by Armin Kielack, with music composed by Elena Kielack. The sheer ambition of bringing an isometric 3D perspective puzzle game to 1982 hardware in 2026 tells you everything about the current state of C64 development. This is not a port or an emulation of something that existed elsewhere. This is purpose-built for the C64 from the ground up.

The game features over 200 levels, a staggering amount of content for any puzzle game. To prevent player frustration, every single level was rigorously tested and verified as 100 percent solvable before release. The massive collaborative effort involved a team of level designers and checkers: Yippee, Marleen, Shirls, Janene, Breanna, kielack, gianna439, jimbo, bob50, rabbits2, punkin514, starwars, arg410, tleit004, prabakaran, tumshee, CallumMclellan, sha718, and pokemaster99 all contributed to ensure quality.

For those unfamiliar with Sokoban, the core mechanic is simple but devilishly challenging. You are a character in a warehouse who must push crates onto marked target positions. You cannot pull crates, only push them. One wrong move can make a level unfinishable, which is why planning ahead becomes critical. The isometric perspective adds another dimension to the puzzle solving, giving the game a completely fresh feel compared to traditional top-down Sokoban interpretations.

The isometric rendering on C64 hardware is a technical achievement. The developers managed to render a 3D perspective using the machine's limited 16 color palette and 64KB of RAM. The sprite animation is fluid, the controls are responsive, and the visual presentation makes each level feel distinct.

The game was released on itch.io as a free download and is fully compatible with MiSTER FPGA as well as all major C64 emulators. It boots from a TAP file for real hardware or emulation, and runs on all Commodore 64 variants. The development process took considerable time and care, but the result is a game that feels polished and complete.

This is what modern C64 homebrew development looks like in 2026. If you love classic puzzle games, retro hardware, and want to see what dedicated developers can still pull out of 40-year-old machines, hit subscribe and stick around. We cover this scene every single week.
