It would be better to have game config to drive configuration based changes to the application

While moving in a direction, we can use key combos (using shift & ctrl keys) to shift lanes or take a quick U-turn in either direction.

There is no way of knowing such key combos and we should figure out a way to document this.

Would be good to have game state saved every 10 seconds or so in-order to avoid loss of progress when browser refreshes.

We need to reintroduce gestures while playing on mobile.

While gamepad is a good addition and is WIP, gestures and swipes are more intuitive on mobile.

Issue is caused due to height and misalignment.

The newly introduced Use Gamepad settings option to toggle between using gamepad and gestures is not working.

The game should auto-pause as soon as it is no longer active.

We should restrict zooming the browser on mobile if we double tap while playing the game.

As of now, length of snake increases with consumption of food and to fill the whole grid would take a considerable amount of time. Should consider increasing the snake length exponentially with increase in time or increase by a constant number (say 5) when we consume food.

It would be great to have some boosts that appear during gameplay and you have to consume those to have an advantage in the game. These boosts will appear randomly for a short time and you have to race to capture it. Once captured, its affect should last for 15-20 seconds giving you an advantage (like slowing down in higher levels or speeding up in lower levels)

Need to give this a thought!

Swiping down reloads the browser and we need to avoid this on mobile devices

We need real-estate for the game combo buttons (#39) and hence we need to remove the score card and figure out a better way to display top scores.

We also need to give a quick info about current modes top score and max. level played.

The game needs a face lift with proper spacing.

Need to restructure and clean up codebase.

• Add linting
• Add TypeScript (if required)
• Modularize the code and break it down into different modes (Classic / Challenge / Maze)
• Concatenate modules and generate minified source files

On a handheld device user should be able to use gestures or enable gamepad to play the game.

User selection should be remembered.

We use predefined set of maze coordinates for the maze mode and it would be nice to have a random maze generated to increase the complexity of the game.

Add prettier to the project to beautify .js files

In classic mode, there is no indication that the level has increased. We should consider displaying that info to the user in some way.

Immediate idea is to add a fading out or bubbling level-up text. Thing to figure out is where to display this.

We should enable haptic feedback for the following

• gamepad controls
• food eaten
• loss of life
• game over (should be a vibration sequence)

Recently we updated event handler key codes and started using event.code instead of deprecated event.keyCode. So, the gamepad's dispatch events might need an update to broadcast event.code instead of event.keyCode

While playing we can pause the game using spacebar and if we press R while paused, the game resets itself without confirmation leading to a loss of all progress made (like unlocking levels) so far.

We should ask for confirmation before resetting the game and losing all the progress in the process.

Note: We cannot reset a game if it is not paused

Pinch zoom gets reenabled when we use gamepad. Toggling the option off disables pinch-zoom again.

In general, it would be great to disable pinch-zoom on handheld devices irrespective of the settings.

We need combo buttons that would enable power moves with gestures

• Need a button for U-turn
• Need a button for lane shift

We need to update the instructions based on the device the game is being played on.
