On the Flipside

A dimension-swapping, 2D micro-metroidvania designed for the Nokia 3310.

About
On the Flipside is a metroidvania made in 5 days for the 2021 Nokia 3310 Jam by a team of 3.

I was responsible for direction, game design, world design, and art.

Process
From the start, On the Flipside was made as an homage to the classic NES title, Metroid.
While my team was a bit nervous that the theme reveal would throw a wrench in our plans, we had high hopes that wouldn't be the case. So when the jam theme was reveled as "on/off," we knew we could make it work.

After some deliberating, we decided to give both the alien planet and the Flipside a unique look, despite the limitations of the Nokia 3310's color palette.
For the alien planet, it's split into 2 visually distinct areas—the surface and the underground. While their sprites may be different, they're both are colored the same: dark background, light accents.
The Flipside is, well, flipped!

Now, what's a good metroidvania without some enemies?
While On the Flipside certain has its fair share of 'em, enemies are more obstacle than opponent, serving primarily as platforming challenges to overcome.
Each enemy does their own thing.

Once a good chunk of the game's design was locked in, it was time to start building out the world. For reference, every red rectangle is 84 by 48 pixels—the size of a Nokia 3310's display.

While the planet looks pretty barren from these sprites, keep in mind: what you're seeing is only half the picture!
Not included in these sprites are: platforms, enemies, and collectables. Which is wild, because collectively, that's like half the entire game!
As I made more and more screens, the guides got harder to maintain.

After I created each one, pieces were combined in-engine to create the alien planet of On the Flipside.

I'm a big fan of pen and paper, so a lot of my early ideation was on various notepads scattered around my house. The concept below was for the first part of the underground bubble caverns, the little area on the far right in the second set of pictures above!

Can't forget to mention the title screen! Just like the planet, it's come a long way.
