The Most Impactful Tool In Our Game Studio

Efficiency graphic

After a productivity analysis, we found that time lost on compiling was the single biggest bottle-neck in our workflow.

That's when we developed our Hot Reload solution, one that would also be compatible with the large size of our project (2M+ lines of custom code).

3 years of battle-testing later, it's helped us accelerate our project, release, update and improve our game, Mobile Minigames - with more than 3M downloads worldwide to date.
