Description

The game is an unofficial sequel/remake of Round 42, an 80's PC shareware space invaders shooter type game:



the original game is unplayable on modern hardware without some kind of emulation as it was designed to work on a hacked CGA text mode allowing 16 colors.
You can find the original game on abandonware sites or play it online using DOSBox emulation sites:

Gameplay

Fight waves of aliens descending from the top of the screen, increasing in speed as their numbers decrease.
Each level has its own type of aliens with different appearance and movement pattern.
Every 3 waves there is a vertical tunnel level where you must reach the exit without hitting the walls.
Besides your default ammo, you have a limited supply of auto-aim lasers and a self-destruct button allowing you to sacrifice one life to clear a level.

Development

I'm using the Godot game engine and in keeping with the spirit of the original game, I'm not using any textures so everything is going to be made out of color rectangles.
While the game will have new levels, sound and a more modern design, I'll try to keep the look and feel of the original.

I'm starting with the tunnel levels. The level is dynamically generated based on difficulty parameters such as tunnel size, turn length, angles, etc. Unlike the original game, the level has vertical scrolling, allowing a longer tunnel.

Current work in progress of the tunnel movement:

Update #1

Added the first shooter level based on the original's first level but without the rapid blinking enemy colors since I don't want to trigger epileptic seizures.
Finished the shooter level logic which will apply to all shooter levels, added levels transition and basic enemy logic which will be used for all the enemies along with their own unique behavior patterns.
Added the auto-aim laser fire. Currently working on the self destruct feature and the new enemy types for the other shooter levels.
