Before we start
Do you build mobile apps for YouTubers as well as games?
Yes. Depending on the channel’s product idea, we plan iOS and Android apps with the interface, content flow, accounts and server work they need. The brief defines which features belong in the first release.
Can we design a character together?
Yes. We can start with its personality, appearance and role, then agree the artwork, animation and gameplay scope.
How are cost and delivery dates determined?
We scope the platforms, mechanics, characters, levels, animation, backend and approval stages. The proposal and schedule follow the agreed brief.
What should I bring to the first conversation?
A channel or brand link, audience outline, any character artwork, game references, target platform and intended launch date are a useful starting point.
Who is this service for?
YouTubers, creators, brands and agencies commissioning a game around their own character, mascot or original idea. A channel or brand link and target platform are enough to begin the discussion.
Are the portfolio examples YouTuber client projects?
WordQuest and HueWeave screens come from our own products; AntSort artwork comes from our own development project. They are not presented as completed YouTuber partnerships or projects for another brand.
Real examples from our own projects
These images come from the SourSpark portfolio. AntSort’s character artwork is a development asset; WordQuest, HueWeave and AlbaPin images are genuine product screens. Each example links to its own project page.
Genuine SourSpark product screens; images retain the app’s original language. Some original WordQuest store artwork still shows its former name, WordTrail.
AntSort →What do these project examples demonstrate?
WordQuest: Word Search →
Actual word-puzzle screens and app icon from our own product. A reference for discussing interface, puzzle presentation and level flow.
HueWeave: Connect the Dots →
Actual colour-connection puzzle screens and app icon. A product reference for touch controls and clear goals on small screens.
AntSort →
Our development project with original character and environment artwork. These source assets illustrate visual identity and world design.
SourSpark · HTML5
From character to gameplay: a live HTML5 demo
Guide the red ant, collect the food and reach the queen. Three short levels bring character, missions and progression together in one browser experience. No download or account is needed.
The Queen’s Trail
Tap a square next to the ant or use the arrow keys. Collect all the food before going to the queen. You cannot cross the rocks.
Start the demo to open the first mission.
Story and level sequence
First supplies
The colony needs to prepare for a new day. Collect two food pieces along the open trail and take them to the queen.
Rocky trail
Rocks are blocking the shortcut. Find a way around them and bring three food pieces to the queen.
The big delivery
The final delivery takes a longer route. Gather four food pieces to finish the colony’s preparations.
This is a SourSpark studio prototype built with original character, food and background artwork from the AntSort project files. It is neither the store version of AntSort nor a game made for a YouTuber client.
What can you inspect in this example?
Character and mission
The ant, queen and food share a clear purpose. The visual identity helps players understand what to do.
Growing level scope
The number of collectibles and obstacles changes across three fixed maps. Completing a mission unlocks the next level, and each level can be restarted.
Working browser interaction
The game runs on this page. Try touch, mouse and keyboard controls. The demo does not require a server account or a store link.
The demo illustrates a short HTML5 game mechanic. It does not demonstrate iOS or Android app packages, a full adventure, saved player accounts, a reward system or client campaign results. Those are planned separately to suit each project.
Who leads the project?
SourSpark is a mobile app and game studio based in Istanbul, Türkiye.
Çağdaş Ekşi leads SourSpark’s work. His experience in backend systems, servers, mobile apps, SEO and marketing helps connect game production, launch preparation and measurement planning.
What should you share for a quote?
- Your channel or brand link and the characters you have permission to use
- Audience, game language and your choice of iOS, Android or HTML5
- The player’s main action and the first level’s objective
- Initial level count, target date and budget range
- Source-code handover, maintenance, store launch and measurement needs
