I wanted to build a simple drawing tool similar to Microsoft Paint or MacPaint and with instance I had a working prototype within seconds and something with great user experience within a few minutes.
Instance helped me ship the prototype of my color puzzle game (Hued) in under 24 hours.
I was amazed by it at first sight. I wanted to build a game, and instantly the Instance made that. How great!
