Bringing emacs' greatest feature to neovim - Tetris!

This plugin is written in Fennel using Olical's project Aniseed for creating the project structure, and as a library of helper functions and macros. The game compiles to Lua and uses Neovim API functions, so Vim support is not currently a goal.

nvim-tetris is a work-in-progress, and is not feature complete.

How To Install

Prerequisites: neovim
You can install the plugin just like any other Neovim plugin. I personally use vim-plug.
Another way to install would be to just clone this repo into ~/.local/share/nvim/site/pack/*/start/, where * is whatever you choose (I use "alec").
After installing, you can launch a game of Tetris using the :Tetris command inside Neovim.
If your colours look weird, ensure you are using a terminal which supports true colour, you have configured tmux for true colour support if you are using tmux, and you have the termguicolors option enabled in Neovim.

Controls

Left Arrow: move left
Right Arrow: move right
Up Arrow: rotate piece
Down Arrow: soft drop
Space Bar: hard drop

What Works

Core game functions including controlling the current piece, clearing lines, and gameover when you run out of space
Piece shadow showing where the current piece will land
Level progression - you progress a level every 10 lines cleared, and the game gets faster with each level
Short delays when the piece appears and when it locks. The locking delay resets when rotating or moving your piece, to make gameplay more fun at high speeds
Correct rotation behaviour including wall-kicks according to "How Guideline SRS Really Works" from https://harddrop.com/wiki/SRS (this means T-spins work)

Next Steps

Add border showing current level, current score, next piece, saved piece (and add logic for saving pieces)
Add pause screen (with options to resume game, start new game or quit)
Add game over screen (with options to play again or quit)
Add intro screen which shows controls
Add logic for score

Tetris messing with my EndingWhiteMatch
I have the following config in my .vimrc

hi EndingWhiteSpace ctermbg=52 match EndingWhiteSpace /\s\+\%#\@<!$/

This highlights ending whitespaces in a dark red color. This does not work anymore after installing nvim-tetris.

Preserve colorscheme

Set ctermfg fallback colors for compatibility if the user doesn't have termguicolors set. Also don't set termguicolors, to avoid breaking users' colorschemes.

Feature Request: Start the game at a higher level
The game seems to be very loose in the beginning because of the drop speed. Would it be possible to start the game in a faster or higher level? It would be nice if we can set the level when starting the game.
