The game is basically Space Invaders, but with a twist: it tells the back-story of the aliens through cut-scenes as you play. It also has two possible endings, one of which is rather unconventional by video game standards. You can try it out, or find out more, here:
- Post-competition version (fixes some of the bugs in the competition version)
- Competition version (this is what I submitted for the competition)
- Ludum Dare page (vote for it if you can!)
- Source code
What went rightI made a game! There was a low point where I thought I'd have to quit the competition (see the "what went wrong" section), but in the end I came through and got a game finished - and while it's not going to win the competition, it's definitely something I feel proud of.
In particular, Invaders is the first game I've done which tries to tell a story & I think it was successful. Most of the people who've commented on it seem to have got the humour and enjoyed the twist that the story adds.
On the technical side, the code I added to show the dialogue during the cut-scenes actually turned out to be useful for way more than I originally thought. I ended up also using it for spawning aliens, checking victory/loss conditions & transitioning between cut-scenes and play. Just a small amount of code, but so handy! I'll definitely be keeping this around for future comps - in fact, it's general enough that I should be able to reuse it pretty much unchanged.
What went wrongThe first idea I came up with after hearing the theme was a game about the predator/prey relationship between wolves and bison, inspired by this clip from the BBC's Frozen Planet documentary. My head was filled with grand ideas about realistic 3D snow-filled environments, tense chases and even tenser standoffs, smooth lifelike animation... You get the idea. The game I somehow thought I was going to make over the next 48 hours by myself, would probably have been about 6 months work for a small team.
Unfortunately it took me all of the first day and most of the following night to accept this. By the time I finally did, I thought I might have to quit the competition. This was a real emotional low point. When I started to think positively again, and came up with the idea for Invaders: Evolution, I only had about 12 hours left to do it in so it turned into a real rush job.
That meant things had to be cut, just so I could get finished on time. Music was the first thing to go, followed closely by sound effects - any attempt at audio at all, in fact. Shame, because I think some cool retro-sounding space invader noises would have really helped with the atmosphere of the game.
The other thing missing was any real relationship to the theme. Apart from having the word "evolution" in the title. Maybe it's an evolution of the old Space Invaders formula? Pretty tenuous...
The main thing I learnt from this is that I need to spend more time thinking through a game idea to see whether it's actually doable in 48 hours. A bit of time thinking up front can save a whole lot more time later if it prevents you from going up a dead end.
Up 'til now I've avoided doing any kind of time management for my Ludum Dare weekends apart from a vague idea of using day 1 for code, day 2 for assets & polish. I always thought it would make it more like work, less like fun. But with hindsight, the fun actually comes from making something good - and time management helps you to do that. So for the next LD I think I'll try coming up with some estimates and a rough schedule before I start work on an idea. If the schedule won't fit into the 48 hours, well I'll just have to find another idea.
To me, Invaders was a qualified success. I think it could have been a lot better if I'd been able to spend all of the available time on it, instead of just a fraction at the end. I've already greatly improved my basecode as a result of this competition, so my mission for the next LD will be to use my time more effectively. In particular, to make sure I don't have to throw all my work away after the first day.
