Marbles Tree
By Irregular ShapesThe Pitch
Marbles Tree is a survival city-builder in which every resource physically travels as a marble. You grow a colony of squirrels, build your transport networks and get your community ready for the seasons ahead.
Now in late production, the project is led by Irregular Shapes, the studio behind City Tales, which has sold over 32,000 units with more than 90% positive reviews.
Marbles Tree sits in a nearly untapped niche, combining city-building with physics systems, with an instantly recognisable mechanic that is particularly well suited to video content with strong viral potential.
Market & Traction
Market Size
City-builder, automation and survival are among the most resilient, high-retention PC/Steam genres: the segment's revenue is growing +42% per year, and the physics-logistics niche keeps producing breakout hits.
Proven traction & clear path to market
Marbles Tree reuses the City Tales pipeline and is already near feature-complete, with 15h+ of playtime: most of the core product risk is retired before the campaign. The Steam page is revealed in late 2026, which makes wishlists the KPI to watch.
Market Comparatives
Potential return if Marbles Tree were to sell the same number of units as each of these comparable games, in the balanced scenario.
The Team
Marbles Tree rests on a rare pairing: Rémi Malet, a CEO trained at École Polytechnique, France's leading engineering school, leading a creative core that has worked together since 2022. A solid business profile backed by a team that knows how to finish and ship.
- Already shipped a PC city-builder (City Tales) on Steam: proven ability to build, launch and monetise in this exact genre
- Dedicated in-house team across code, 3D art, design, UX/UI and original music & SFX
- Reusing a proven art pipeline and tech from City Tales, de-risking production and cost
- Near feature-complete build with 15h+ of playtime, ahead of most crowdfunding-stage projects
- Strong art direction and a signature, highly watchable mechanic built for organic reach
Strategy & Roadmap
Go-to-Market Strategy
Positioning:
- Genre: Systemic survival city-builder × automation, with physics-driven logistics.
- Creative DNA: Inner-child playfulness - marbles, treehouses, humanised squirrels - with elegant engineering depth.
- Unique Value Proposition: A tangible, physical marble economy you can watch rolling: readable, satisfying, highly shareable.
- Ambition: A flagship IP for Irregular Shapes, PC/Steam first, with post-launch content and platform-expansion potential.
Audience:
- Target Player Profile: PC/Steam players of city-builders, colony sims and automation games (Timberborn, Against the Storm, Factorio, The Wandering Village) - systems-driven players who enjoy optimisation, creativity and "one more idea" logistics.
- Crossover: A cozy / wholesome audience reached through the squirrels-and-tree fantasy.
- Market Size and Trend: A resilient, high-retention niche with long sales tails.
- Target Regions: PC-first, English-language; priority on US, Germany, France and UK (mirroring genre and City Tales sales distribution), plus a dedicated partnership for China.
Marketing plan:
- Pre-launch: Steam page and reveal at a major digital showcase; wishlist-driving devlogs and art clips; content-creator and press outreach through Not A Shark Company; Steam Demo during a Steam Next Fest.
- Launch: Streamer and influencer push leveraging the marble economy's watchability; festival timing; launch-day discount; day-one patch cadence.
- Post-launch: Content updates timed to Steam sales and fests; bundles with overlapping genre titles; community events.
Commercial and distribution plan:
- Public Game Price at Launch: $29.99 (to confirm), in line with genre comparables ($24.99–$33.99).
- Platforms: PC - Steam first (single-player); additional stores and platforms considered post-1.0.
- Release Strategy: Direct 1.0 launch, followed by post-launch updates and paid DLCs.

Sign inIrregular Shapes partners with publisher Radical Theory for the launch of Marbles Tree
16 October 2026 · by Ivan Marchand, President of Gamevestor
Irregular Shapes, the studio behind Marbles Tree, has partnered with publisher Radical Theory to support the game's commercial launch.
Why is this good news?
Creating a great game is not enough: it also needs a successful launch and the ability to reach the right players.
Radical Theory will support Irregular Shapes with its go-to-market strategy, marketing, communications, press relations and influencer outreach. This will allow the studio to remain focused on development while a specialised team prepares the game for market.
This partnership strengthens one of the key factors behind the potential commercial success of Marbles Tree: its ability to reach the right audience when it launches.
Having assessed the strength of the studio, the advanced state of production and the game's market potential, the involvement of Radical Theory represents another encouraging signal for the project and reinforces our confidence in its launch strategy. It does not, of course, guarantee the game's future performance, but it significantly strengthens the conditions surrounding its commercial launch.
Nearly 50 investors already on board

A little over two weeks after opening to the public, the Marbles Tree campaign has brought together nearly 50 investors. Thank you all for your trust.
The campaign continues: you can still take part from €100 and receive a share of the game's revenue, depending on its commercial performance. Please note that the studio may close the fundraise as soon as the €160,000 target is reached.
