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 owned our game design, level design, and art.

Process
From the start, On the Flipside was made as an homage to 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.

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!
The bubble caves are an homage to Super Metroid.

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, you're only seeing half the picture!
Not included in these sprites are: platforms, enemies, and collectables.
As I made more screens, the guides got trickier to maintain.

After I created each one, pieces were combined in-engine to create the alien planet of On the Flipside.
While it worked for the jam, this method is far from ideal. Using tilemaps is typically the best workflow for 2D sprite-based games, so my apologies to any devs looking at these images in abject horror!

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