Concept:

Horizontal shmup, based on the novella by H.P Lovecraft.
You play as a version of R. Carter, in his quest to find the sunset city of Kadath.
You will have to fight Zoogs, Goos and moon-beasts in order to reach the destination of the gods.

Engine:
HTML5 w/ some framework: I want the game to be playable in a browser. And this is the quickest way to do so nowdays,
also, this is a good opportunity for me to test drive different frameworks.

Graphics:
160x120 resolution;
8x8 tiles;
16x16 sprites;
C64 based palette.
(The entire output will be scaled up to the browser window size, but this will allow me to draw stuff quicker).
Tool: jpixel:  I'm really liking the ability to preview animations inside the drawing program and also to be able to export spritesheet and tilesets.

Sounds and Music:
TBD. I plan on using at least one 8bit chip for music.
I would like to venture into FM, but only if time allows, otherwise, i'll most likely stick to the PSG (SN76489) chip for everything.

Scope:
- At least 2 levels with 2:00~ minutes of gameplay each.
- Min. number of enemies: 3.
- 1 boss.
- 2 songs.
- 3 SFX (shooting, and 2 explosions).

Bonus (only if the scope is met):
- upgrade-able shots. / power-up system
- more enemies.
- more bosses.
- more levels.
- decent scoring system
- more stuff.

Levels:
Stage 1: Enchanted Woods
Cavern with logs and trees.
Enemies: Zoogs, plants and something else.

Stage 2: The town of Ultar
City-like.
Enemies: plants, turrets? and something else.
Boss: Atal, the patriarch.

Main Ship:
Some sort of bio-mechanical/organic submarine to navigate the dream-land.

Some tiles:
These are place-holders and will be substituted in time.

What i have so far:
- Horizontal scrolling scene, with a controlable ship.
- A shoot button that works.
- Some tiles.

Next steps:
- Implement one enemy.
- Draw some bullets (shots)

I needed some enemy sprites in order to test enemy placement and movement, so here they are:

Some sort of abstract, lovecraftian creature, with multiple disjointed eyeballs:

A very low-res rendering of a moon-beast:

These are place-holder, but will most likely be in the submitted game, i think their weird aesthetic matches what i'm going for with the game.

I'm still working on entities. I added 2 types of enemies similar to each other, but they are mirrored in their behaviour.
I need to draw some explosions to make the killing of the enemies more satisfying.
Next step is adding enemies that can shoot back at the player.

Overall, i think i can make a fun little game. I want to get started on songs/sfx during the weekend. We'll see.

Entities pretty much done.

I have 3 types of enemies configured.  I have the first level layout ready.

Now, i need to finish something playable (at least 1 level), add sfx and music, and then polish/add if i can.
If people enjoy this little game, i might try to fully flesh it out.

Level 1 is pretty much done.

I'll focus on finishing that, to release something before the deadline.

So, it will be one level only. I need to activate player death, and i need to create some sort of explosion sprite today.
SFX are pretty much done (white-noise ftw).
But i still need at least 1 music track.

After that, is just adding some text/score and simple stuff.
I think i can finish and package 1 level before the deadline.
