This fork adds option to play with hjkl instead of arrow keys.

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.

• 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.

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

• 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)

• 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
• Configuration
• Documentation
• Tests
• Stretch goals: music, leaderboards?, ...
