🚀 Feature

Motivation

Players should be told how to play

Implementation

It can be a button on the main menu that opens a popup explaining the controls.

Or it could be a popup that is visible for a few seconds at the start of a match

🚀 Feature

Extra lives (consumable item)

Motivation

As the game progresses players will have a chance to randomly get a life moon to regenerate a lost life.

Implementation

• The life moons will occasionally spawn and move down in a straight line (it should be random but strictly after a given timeout after the last life moon).
• They will regenerate a lost life or add more on top of the 3 starting lives. although a player will have a max of 5 lives.
• There will be at least 1 of these guaranteed at the start of the boss fight and at the end.

Additional context

The probability of spawn - TBD.

🎨 Design

Assets for #1

Implementation

• The ship
• New laser color
• Omega laser beam

Additional context

Pixelart in asesprite. A little bit bigger than the artillery ship at scale (check artillery asesprite file to determine canvas size)

🚀 Feature

Upgrades for the lasers

Motivation

To allow the player to have a better chance at surviving late game.

Implementation

• tri-laser
• golden laser (x2 damage)
• rainbow laser (x3 damage) -- one guaranteed at some point during the boss fight
• immunity cloak (immune - pulsing for a few seconds)
• Extra ideas?

Additional context

Probability of spawns for each upgrade - TBD

🚀 Feature

Motivation

Players want to be able to edit the game controls

it should be a main menu option, it could be in the controls popup #7

🎨 Design

Design for life moons

Implementation

A simple animation of a shinning white-ish light blue blob.

🚀 Feature

Boss fight after reaching a milestone

Motivation

Brings a greater objective to the game and a reason for players to keep trying to reach a win against the boss

Implementation

After a player reaches a given amount of kills or score or kills of the hardest enemy ship (artillery) the boss fight will start, its health bar will replace the invasion progress bar and the player cannot lose by invasion.

The boss will shoot lasers from several cannons and shoot bombs from the central cannon. When its health decreases to a certain point it will shoot omega laser beams that take up most of the screen.
Additionally it will occasionally deploy lower level ships (common, gliders and fasts).

Additional context

Easter egg: after killing it the game will start over (without resetting the speed) and the player ship will become golden.

🚀 Feature

Motivation

Gun debuffs to be evaded

Implementation

• double-laser (split to the sides)
• slow weapon
• slower ship
• Extra ideas?

Additional context

Probability of each debuff - TBD
