-## Introduction

-![TK2048 V2.0 title screen](pics/title.png)
-
-This game is an excuse and a testbed for the development on the Microdigital TK2000 clone [I recently built for myself](https://github.com/hkzlab/TK2000_Build_Notes).
-
-My primary objective with this game is building something where I can add support for all my expansion boards (well, at least where it makes a sliver of sense) so I can test and PoC them, beside,
-I want to experiment with the [Calypsi toolchain](https://www.calypsi.cc/).
-
-I decided for a port of 2048, the now-classic tile sliding game, as it provided several advantages as a first time/playground project:
-
-- Doesn't need complex graphics hardware or advanced artist skills
-- It can be drawn in B/W with static graphics, but animations and colors can be added in the future
-- Sound is not needed either, but can be added for simple events like a tile slide or a button press
-- The game logic is pretty simple
-- Not CPU or memory intensive
-- Can be expanded with support for additional hardware (sound cards, video cards, timers) if so desired, but it's not necessary
-- Floppy drive can be potentially used not only to load the game, but also for saving the high score

-### Support
-
-If you wish to support me in building new hardware and software for old machines, [throw a few euros in my direction via Ko-Fi](https://ko-fi.com/hkzlab) ☕!
-
-### Current state
-
-The game is playable, and the following features have been implemented:
-
-- B/W mode
-- Single graphical tileset
-- Crude sound
-- Control via keyboard
-- 5x5 grid, with randomized start and new tiles
-- Game save/load
-- Highscore saving
-
-## How to play
-
-- You can move the tiles using the cursor keys
-- `CTRL-R` during the game will clear your score and restart
-- `CTRL-S` during the game will save the game on floppy and let you continue
-- `CTRL-L` during the game will load the previous save from floppy and let you continue from there
-
-The game ends once you reach a tile with a value of 2048.
-
-### Floppy version
-
-Just put your floppy in the first drive and power on the TK2000. It will autoboot.
-
-## How to build
-
-You need the following:
-
-- GNU Make (I used the one provides by [MSYS2](https://www.msys2.org/))
-- [Calypsi 6502 toolchain](https://www.calypsi.cc/) (tested with 5.10)
-- [AppleCommander](https://github.com/AppleCommander/AppleCommander), "ac" command line version (tested with 1.9.0)
-- [dsk2woz](https://github.com/TomHarte/dsk2woz)

+## The future
+
 I plan to add (optional) support for several expansion boards I'm working on, starting with a VDP board sporting a TMS9918A graphic processor.
