Faster Than Alien : Game submitted

Faster than Alien intro

The game is not entirely ready, but it is submitted nontheless. I’m not entirely happy with the AI or with the control system of the alien spawn in the 3rd phase of the game. Also, for the game to have some depth, there should have been more spaceships and more human units (esp. marines) to explore and hone your alien tactics on.

Also the game is very ugly, but I’m not artist and I simply did not have the time to do serious pixel pushing or 3D-modeling. By minimum the sprites should have walk cycles to all 4 directions, but this time it was not a priority, and therefore, it did not happen.

I’m was quite happy with the tool of my choice: the Jypeli-library. I only encountered one problem caused by the game framework and even that was circumvented quite easily. Coding the game in C# was a breeze, but creating assets takes really much time. Even when I decided to use only minimal placeholder graphics. My respect goes to you fellow LDers who have created really professional game assets AND a game in so little time.

The game consists of ~1000 lines of C# code, 20 or so sprites, few sound effects generated with SFXR. I effetively worked around 12-16 hours, and I estimate that the time was distributed 10% ideas / 40 % coding / 40 % assets / 10% updates, chatting, etc. I have captured the process, so expect timelapse in few days.

Have fun playing and beware the bugs:


Faster than aliens

Time to give a sneak peak to my game. I draw inspiration from the first Alien movie, FTL and 90’ies game Space Hulk. You play as the alien spawn and try to breed (as that is what aliens aspire to do, right?). Unfortunately for the unlucky spaceship crew, this involves taking captures and defending the nest and territory. There will be some casualties for the AI controlled hu-mans, but that should not become as surprise to them – after all, all these dangers are listed in fine print on your contract with the megacorp, remember?

The game happens on a spaceship that fits on a screen. The player starts as a alien spawn born out of a first hu-man casualty. First you have to run and hide until you have grown enough you can try to take an human captive to be used as a host. At this time the humans will probably find out there is something fishy going on, so beware those flamethrowers. Dragging the unwilling host for your offspring behind you, you should find a warm spot in the spaceship to build a nest and start to reproduce. Nesting means you can no longer move, but fortunately you now have alien soldiers and alien drones at your disposal. It is time to be the insectoid mastermind that takes control of the spaceship before the hu-mans destroy your nest or initiate the self-destruct mechanism.

What I have:

  • A spaceship where you can walk around. Built from tiles and loaded from a resource file.
  • A player controlled alien spawn that grows to be a full grown alien.
  • Hu-man crew that wanders aimlessly. If it sees an alien spawn, it tries to catch and kill it. If it sees a full grown alien it will flee in horror.

What I still need:

  • Ability for the full grown player controlled alien to take captives, find a warm spot and build a nest. And indicators for these.
  • A state machine for the hu-man AI as the game relies heavily on interesting behavior of the simulated spaceship crew. Information propagation is also needed so that the first sighting of a full grown alien makes the crew to arm themselves.
  • Game ending conditions.
  • Sound effects.
  • Better graphics produced using Blender if I have the time (probably not).

I will probably not make it as I do not have too much time and the AI stuff is always prone to be more complex than expected. But I will do my best!


“A Cat With Only 1 Life”, status after 1st day

The first day is done for me. I managed to do around 4 hours of game dev today (from 18:00-22:00 local time). Installation of tools took some time and being a family man, 4 hours is what I had so the progress was limited, but this is where I’m at.

The idea is to build a game of a cat with only 1 life (when everybody else around him has the typical 9). How he still can beat the others is something that you will see day 2… (hint: cats are stooopid, but the cat with only 1 life has to be smarter than the rest).

The tools used: Visual C# 2010 with JyPeli game programming library. Paint.NET was used for drawing sprite graphics.

What was produced in that 4 hours was 10 or so sprites and ~250 lines of C# code. (and then I spent another 1:30 to prepare the timelapse, screenshots etc., but where is the fun in LD if you do not share?).

If you are longing to see more of my process, see the timelapse:
