Developer Q&A — Vital Shell, iteration, balance, and what’s next
Answers provided by Marvin.
What was the original spark for the game — and what inspirations shaped its visual style and core gameplay loop?
The original spark for the game was listening to some old N64/PS1 Jungle mixes on youtube. I was curious about game dev and it got me thinking what kind of game would be a fun first project that would match the energy of that sound. There are so many inspirations it would be an entire write up in its own right. Of course PS1 FromSoftware titles were a big visual influence, Cannon Spike on Dreamcast was a huge influence for the framing of a 3D multi directional shooter, Magic the Gathering’s color wheel was a big influence on how to create build identities. Arena shooters new and old are responsible for the genre, so have to shoutout Asteroids, Robotron, Smash TV, Vampire Survivors, Halls of Torment, Brotato, Deep Rock Galactic Survivor, Death must Die.,
What was the hardest part of development, and why?
There wasn’t any one big hold up I ran into. In many ways the game has been carved from a mountain of different ideas. I didn’t have a grand plan that I executed on, I just kind of kept trying things until it felt good and would move on. So it went through many iterations, weapon evolutions, inventory organization style upgrades, large obstacles in the arena with slower enemies, all sorts of different experiments. Many times I’d spend a week building a system only to find it didn’t quite feel right, and I would just scrap it and move on.,

The game feels carefully tuned — enemies, upgrades, and player power all push strategy without losing the pace. What was your approach to balance, and what was the most challenging part of getting it right?
I’m surprised you consider the game balanced! I think it’s a weakness of mine as a developer, something I’m learning a lot about still. I have a spreadsheet with DPS simulations of each weapon in various contexts, and I would experiment with how stats influenced those outcomes. There was this game of designing the systems in a way where all of the base stats would have a similar impact on DPS for a similar quantity of stat. Then conversely, I tried to create abilities that would respond strongly to one stat and fall flat with another. The idea being if you decided to stick with a couple stats, there would be abilities that scaled strongly with those stat choices.,
How has self-publishing been for you — especially in a period where a lot of indie games are launching? What’s been the hardest part, and what surprised you by being easier than expected?
To be honest I still don’t fully understand what a Publisher does, it’s all very new to me. My general approach has just been to follow the wisdom of Chris Zukowski, and it has been remarkably consistent. I tried to make cool trailers for the game and engage on social media a bit to get that initial spark, then of course putting out the Demo and doing a next fest. Aside from that, the hardest thing has been reaching out to content creators, as that’s just a very manual process. Now that I’ve established some relationships and contacts it will be a bit easier for the next go around. The real miracle has just been Steam, getting on popular upcoming and then new and trending really skyrocketed things.,

What’s next? Do you see the game expanding with additional modes or content, and how do you decide what to add next?
I want to make sure I do Vital Shell justice, I’m working on a few new game modes and want to sort out local co-op. However I’m really eager to take what I’ve learned and build something new. There’s lots of asks for more verticality, or larger maps, things of that sort. I’d much rather create something new with those features as a first class citizen, rather than trying to jam them into Vital Shell, which is really balanced around being a simple arena shooter.,
