Blok Copy RX
Platform: Commodore 64
Gametype: Undefined
_________________________

This remixed version was built from the source code for Blok Copy and contains a number of graphical tweaks to make things easier to follow, along with quite a bit of internal tidying. This work was mostly taken on whilst preparing to write the Atari 8-bit port which was released on the same day. The source code for Blok Copy RX on the C64 has been released onto GitHub.

Trivia: To enable the "hidden" PETSCII mode (which was based on the at that point unreleased Blok Copy - PETSCII Edition, hold down the Commodore key as fire is pressed to start the game.

Blok Copy is a puzzle game. The player is at presented with a 5x7 board consisting of different kinds of tiles. At the start each column has only one kind of tile but the tiles will then get shuffled around. The aim of the game is then to restore the board as it was at the start. The player uses the keyboard to move the rows and columns until the board has been restored. Once completed another board will be unlocked. There are ten in total. The time is limited so the player can't take too long.

Shortly after releasing the C64DTV version of the Blok Copy in 2009, T.M.R mailed me a feature complete C64 version of the game using the original PET version's character graphics as temporary placeholders. Then in mid 2011, a video of a beta version of the game with proper multicolour graphics popped up on YouTube, with a comment suggesting that it may be suitable for a 16KB cartridge release. This game is the end result; Cosine's entry for the 2011 RGCD 16KB Cartridge Development Competition. 

The player's objective in Blok Copy is simple; the playfield contains seven numbered and distinctly different patterned tiles arranged into columns of five. At the start of each level the tiles are shuffled around, with the number of moves increasing as you progress through the game. The player must then reorganise the tiles to resemble their starting order against the clock to progress to the next stage until all ten levels have been successfully resynchronised. Blok Copy plays similarly to a two-dimensional Rubik's cube (if you can imagine such a thing); instead of moving the blocks independently, you select a row/column via the joystick controlled cursor and rotate it either up, down, left or right. 

The game has been tested on both PAL and NTSC machines, and works on the C64, C128 and C64GS (there is no keyboard input required to play). It comes boxed with a printed manual, and the cartridge is a transparent split candy-coloured shell containing an internal bright LED so that it emits a glow when plugged in.
