Update from the Kickstarter: I know it's only been 24 hours since the last update, but Lemma is now over 61% of the way to the top 100 games on Greenlight with well over 4,500 yes votes. Thank you all for being a part of this project!

I realized that the 30 seconds of gameplay from the Kickstarter trailer is not enough to really see what's going on, so here's a more in-depth video explanation of the movement in Lemma. Skip to 2:15 to see an explanation of the magical wall-creating, environment-modifying bits.

From the Kickstarter, a quick status update before I talk more about Lemma:

• At the current rate, we are just minutes away from 4,200 yes votes on Greenlight! 56% of the way to the top 100.
• A big thank you to our new backers! There are now 174 of you lovely people (wow) and we're over 32% funded.
• Rock Paper Shotgun covered Lemma yesterday! And with that headline, we've added Bastion to the incredibly long and disparate list of games it's been compared to.
• Kill Streak Media posted a fairly in-depth interview.
• Death By Beta also ran a nice little article.
• In case you missed Caitlin Clark's comment earlier, Lemma was her top pick for Kickstarter games that are "Worth the Wait", along with several other promising-looking games!
• Another great "let's play" video from YouTuber Shake4ndbake.

Okay, let's talk about future plans!

First: I wanted to thank everyone for the amazing support you've shown so far. We're already over 24% funded, which is more than I was expecting this early, so thank you!

Second: A quick update on the Greenlight campaign. We are 26% of the way to the top 100, with 1,918 "yes" votes! Keep on voting, we'll be on Steam in no time.

Third: If you wanted to see more gameplay from Lemma but didn't have time to check out the demo, several YouTubers have posted "let's play" videos of the demo. Draegast has a good one right here.

After an unexpected 24 hour delay, the demo is finally out, and the Kickstarter is live! I'm running on 3 hours of sleep, but here's some things you might not have seen since the last release:

The bouncy cubes are now more like crumbly cubes. They crumble when you touch them.

I've been worried that I don't have time in the demo to introduce every idea I have at a reasonable pace, so I'm thinking of including a "sandbox" map that just enables every ability and throws every idea at the player and lets them play around.

(It's so dark because I still have a pesky rendering bug)

I also realized I accidentally had pre-multiplied alpha turned on for my cloud texture. Here's what it looks like when you use pre-multiplied alpha incorrectly:

And here it is fixed (I also made the clouds fade in over distant objects):

I also distributed a number of mysterious notes around the levels to help flesh out the back story. They're actual 3D objects rendered and lit in the game world.

WHAT COULD IT MEAN? THIS REVELATORY NOTE HAS ADDED HEFTY NUANCE TO THE PLOT AND SIGNIFICANTLY INCREASED MY IMMERSION IN THE STORY.

Other than that, just lots of level design iteration, scripting, and tweaking.

The OODA loop models the way human individuals and groups operate. It goes like this:

• Observe the situation
• Orient your observations in the context of goals, past experience, etc.
• Decide what to do
• Act on your decision
• Repeat!

After the initial act of creation, game developers operate under the same principle. You play the game and observe it, orient that data in the context of your goals, decide what to do, open your IDE, and put your plan in action. Rinse and repeat.

The phone has returned, but now it's in full 3D glory:

Some parts of the levels now build up dynamically when the player reaches them.
