My Game About Animals Surviving Suburban Sprawl

On 17/05/2021

Play as the protector of animals, Potnia Theron, and save the life force of creatures from the ever-expanding presence of human settlements.

TOJAM 2021: FEELS LIKE A RERUN

TOJam’s theme for 2021 was “once more with feeling” and like with many game jam themes one can go anywhere with it. I chose to go into the past. What if we could replay history, but feel more for animals?

For the jam, I made a game in which you guide animal spirits to safer places over the course of hundreds of years. You are Potnia Theron, protector of animal spirits. who awakes when animals need guidance and protection.

Early development in the game

Whenever humanity builds permanent structures the local animals get pushed out of their natural habitat. It’s Potnia’s role to get those homeless animals to a safer place, away from the growing sprawl of humanity.

Animal spirits follow Potnia Theron in the game to get to safety, unless the animals get killed by human activity of course. As time progresses the obstacles to animals change, starting with snares and ending with vehicles and invisible pollutants.

The game asks: can animals stay safe despite the unsustainable suburban expansion in North America?

Motivation for the game’s theme

TOJam, like most game jams, are best done with a team. I went solo for this jam, which meant that the theme was entirely up to me.

I looked back at game ideas I’ve had in the past and combined one of them with the theme of the jam. The original idea was to create a corridor for humans to travel through as if they’re animals stuck in a preserve corridor. This was directly inspired by a day trip to Mono Cliffs outside of Toronto where I saw the sign pictured below.

Mono Cliffs

The other idea stemmed from growing up in the suburbs where developments are named for what they destroyed (Deer Meadows, Glen Field, Forest Walk, and so on). As a teen I was told a benefit of the suburbs lies in the fact that it’s all nature around us and it’s not polluted like “gross” cities. That was so wrong.

I won’t go into all the reasons why modern car-based suburbs are so problematic so here’s a quick list to other resources:

So I decided that I would revisit the suburbs “once more with feeling” and make the player protect animals.

The start of the 1920 level in the game

The game spans hundreds of years, from “long ago” to 1820 all the way up to 2020 (and beyond!). Players show up at an increasing rate, at first it’s 100 years, then 50 years, then 25, and so on. This captures the increasing rate of environmental damage done to our planet from suburban expansion.

From ambitious experimentation to… walking

On this front, I’ll admit that my experiments failed (or worked, since I got results). I set out to try:

to make escort missions interesting;
integrating real-world geographic information;
trying some new toys from the Unity asset store.

Potnia Theron game level 2009

Escort missions are a slog for a few reasons, one such reason is that the NPC being escorted is always a slow idiot who does all the time. Sounds like ducks or rabbits right? I wanted to try making an escort mission that used shortcomings to its advantage. The followers in the game respawn on their own, so follower death only impacts the measurement of success and not failure of the mission.

I spent time making obstacles which eliminate the followers and even building a death counter. These were more of a hassle than something that enhanced the game play. Just like in escort missions.

Using real world data is something I’ve done before with Lethal Strike; this time I wanted to use it on a more human level instead of hundreds of meters in the air. My original thinking was to use actual suburbs from the Greater Toronto Area (GTA); however the tool I used to create the maps lacked the fidelity needed. I compromised by only using real-world topographic data.

So yes, the game is set in the Toronto area using real world map data.

New neighbourhood in the suburbs.

I went too far with the “toys” I got from the Unity asset store, so many that the project size balloon to be too massive to package for HTML5. I thought using existing assets would make up for doing the jam solo, but I think it would have made more sense to just start from scratch next time. Of course, some of the assets are useful for other projects I’m working on.

After all of this experimentation and failed game play outcomes I chose to categorize the game as a walking simulator on Itch.io.

Stardoz! My Game Which Uses Heartbeats To Spawn Enemies

by Adam Clare

On 20/05/2015

In Design, Experimental

First version of Stardoz

Stardoz is a crazy experimental biometric-driven game I built at TOJam a few weeks back. In the game you fly around in a spaceship shooting at giant floating heads and hands. It’s similar to many flying in space combat games.

The catch is that your heartbeat controls the spawn rate of enemies. The pulsing red border on the screen shows the player’s heart at work.

If floating heads seems familiar to you, it’s because you may remember the movie Zardoz starring Sean Connery. Just watch the trailer to see how zany the movie is.

Really, the gameplay is similar in play insofar that “the gun is good” and that one survives by ‘killing’. It’s very simple gameplay with a neat twist. I made Stardoz to test out some space-based game mechanics and to incorporate some biometric data into a game.

Playtesters have liked the heartbeat spawn mechanic and only one player took issue that the game is hard for people with high resting heart rates. I’m still tweaking the spawn rate but it’s alright for the most part.

The art confuses players and that’s a design goal of mine. I wanted it to cross between the ridiculous and the overly-symbolic. Thus, instead of a score it lists how many egos you’ve destroyed and how many emotions you have. .

You are flying through space (or is mindspace?) destroying representations of human forms. In some cases it’s heavy handed and in some ways quite subtle (only one person has figured out the symbolic placement of the TOJam goat).

Getting the Heartbeat

With the excellent help of J Lee, I was able to get an Arduino Uno board to work with a pulse sensor which meant that heartbeats could be tracked using Unity. The heartbeat is tracked using this pulse sensor which was really easy to connect to the Arduino and to configure it into Unity.

“Fun fact”: for Windows use COM4 and /dev/cu.usbmodem1421 for Macs as the port for Unity to talk to the Arduino. At least this is what worked for my setup. Results may vary.

The pulse sensor goes around the player’s finger and surprisingly doesn’t interfere with gameplay controls. It can be attached to the player’s ear but it just feels weird.

Here it is in action around the left index finger of a player:

Next Steps

For this game will be to see if I can get it working with the Apple Watch (or Android Wear), if it works maybe I’ll release it for anyone to play. In the meantime I’m hoping to show it at upcoming events.
