EurogamerAs is true of all games. Do you think the restrictions on each year's project were there to force you to be more creative, rather than just slowly introduce new tech?

Kim Swift

Well we were learning game history at the time to as well, one of the first games we had to play in our games class was Zork.

EurogamerThat's good to know.

Kim Swift

But mainly it's there to help get your feet wet. When I was going to school there we weren't allowed to use any other engines like say Source or Unreal Engine. So we had to build our own engines and heading right into DigiPen we didn't know how to use Direct3D straight off. So text-based was a good place to start.

EurogamerMakes sense. So three of your team were already together. Did you stick with each other for the rest of the years?

Kim Swift

Jeep, Garret and I stuck together and then Dave [Kircher] joined in a couple years later. Then the artists, Realm [Lovejoy], Paul [Graham] and Scott [Kintworth] didn't join until our Senior year. And that's the whole Narbacular Drop team that eventually went on to Valve.

EurogamerSo it's the fourth year, and you're doing 3D and physics. Has anyone already had the idea for Narbacular Drop?

Kim Swift

The idea for Narbacular Drop started the summer before Senior year [that's the fourth year - Ed]. We decided that we wanted to get a jump-start on the game and actually have a good plan in place for once.

EurogamerSo what was the original seed behind the game? It's tempting to assume it was the portal. Did that come first?

Kim Swift

Yeah, pretty much. Dave had been working on the idea of having these portals you could look in and see out the other. And we all pitched in to try to find a good way to use them. Having the game be an environmental puzzler was somewhat of a mash-up of a couple game proposals.

EurogamerDo you remember what they were?

Kim Swift

Honestly, not really. I know I proposed some sort of puzzle game with fish.

EurogamerDo you still resent the lack of fish in the finished game?

Kim Swift

Not really, we had Lava Turtles. That was way better.

EurogamerHave you played Narbacular recently?

Kim Swift

It's been awhile. I think the last time I played was when I was getting screenshots for a GDC presentation a few years ago.

EurogamerWhat do you think of it now when you look back?

Kim Swift

Wow, it's very brown.

EurogamerThat must be how John Carmack feels all the time.

Kim Swift

Nah, more like I've learned so much since school. And certainly giant heaping piles of gratitude. And the brown thing too.

EurogamerI remember the first time I saw it. A colleague from a rival publication showed it to me, excitedly. "Look! Look at this!" and then played with infinitely looping portals. It was a moment of: "Oh yeah! That should have existed since the beginning of time."

Kim Swift

Too bad they don't actually exist in real life.

EurogamerYeah. This is technology someone should be working on. Although I know for sure I'd permanently be throwing the wrong portal and getting myself stuck in small rooms.

Kim Swift

Or getting extremely motion sick.

EurogamerSo, then came that magical moment.

Kim Swift

Yep, us coming to Valve.

EurogamerWhat was your plan before that job offer?

Kim Swift

Well I was interviewing and hoping I might get a job with Crystal Dynamics actually. So basically looking for a job.

EurogamerAnd why didn't that happen?

Kim Swift

DigiPen holds an expo for game developers to come in and check out the work of graduating seniors. So Valve sends over a couple people to take a look. Robin Walker actually was the one who talked to us. First he proceeded to tell us everything we did wrong. He also commented that the game was very brown. And after we were sufficiently pulverised, he gives us his card and says good work, and stay in touch.
