Surrendering, Before Time’s Up

My game’s in early, didn’t want to wait until the last minute and be unable to reach the site when everyone scrambled to submit all at once.

So here it is!

play Intersection

Controls: WASD, arrows, R to restart

Goal: Get the two players together.

This is end-game stuff, the objective is to 'get together'.

 What is this thing?

Intersection is a spacial puzzle game with a mechanic based around the intersection of environments. It’s for two-players one-keyboard, but can be completed by one person without any trouble.


My idea for the theme ‘tiny world’ was the way two people see the world when they’re really into each other. For them, the world can become the intersection of their two perspectives – that is, a tiny, unique little world.

Whether or not that translated into the game is up to you to decide, but it also works on a maths level: the puzzle can be thought of as a 3D maze being projected into 2D from two different perspectives, with the player(s) exploring the ‘tiny world’ formed by the intersection of these perspectives.


I had about an entire day set aside for building puzzles for this mechanic, which I didn’t do. Instead, I spent that time thinking about the game and how difficult it would be to write legit puzzles for it. For example:

  • If the two players combined have sides touching walls in all directions, neither can move. This is a huge source of frustration, and can easily creep up without warning.
  • If, on the other hand, one player is not touching walls on at least two sides, the other player can walk straight through the rest of the puzzle with little effort.
  • This means that the puzzles need to be straight paths — so much as a branching hallway allow the puzzle to be ‘broken’. Interestingly, though, each path can be linear without making the play-space linear: the two (linear) spatial dimensions are combined with a third dimension of movement constraints, which changes as the other player progresses.

tl;dr: Puzzles would be really hard to make, but are possible (and interesting).

Anywho, enjoy, and thanks for playing! 😀

Here’s my LD entry page.

Starting Day 2

Coming up on the ten-hour mark. I’ve got the mechanic done and sounds in, looking good. :) You can fiddle with it here, today is going to be spent working on puzzles. Left player uses WASD and right player uses arrows (it’s all just as do-able by one person, though).

Weird effect

Here's a weird 'visual reverb' thing that's going on as a consequence of the core mechanic.

There are lots of ‘immediate and unforeseen failure’ situations that I’m going to have to avoid, and lots of really easy layouts that I’ll have to use carefully. But also lots of really interesting spacial puzzles, I hope!

Good times!

First LD – Day 1 Done!

Spent the first ~20 hours of my first LD without a good idea, but I’m on-pace for day 2!

Day 1 progress

This is as pretty as it's getting. :/

It’s a two-player one-keyboard puzzle game, and it looks like I’ll be spending day 2 making puzzles/audio.
