Really great app, instructions are basic, easy to use and great for learning. Bottling plant was super addition. animation of traffic crossing would be expected, but the I/O playground (without animation) layout leaves plenty of room for creativity.

I enjoyed this app! It's a bit buggy every now and then, but I would just save often. Other than that, I wish it had more tasks to do. The two challenges it currently has were fun to do. Adding the advanced tasks to the one challenge was a great addition. I hope to see more in the future! Thank you for making this app. It's better than the one I tried before this one. Finally, thank you for helping me in my learning! Thank you for not trying to take my wallet to do it.

UPDATE: A NEW VERSION was just released December 20. I plan to add a new animation in late January. Jason, Thank you for expressing your appreciation so well and the 5 stars. You did well to complete the second programming exercise, as it was intended to be a fun and challenging one. David

Easy to use and a great help in refreshing my knowledge I learned 10 years ago. Beginner freindly too. Only critique would be making inputs and outputs able to activate multiple sources at once.

Thank you for taking time to write a review and your 5 stars. Your request for a single rung to control multiple outputs is a good suggestion. I just haven't found a way of implementing it yet. David
