So, not sure if you can see this, but I just recorded a sample of its performance on my screen. (This is after tweaking it as much as I could to get it to run smoothly, to no avail...)
Pay attention to how jerky the movement of the lines that scroll down the screen look. It's practically unplayable like this, and definitely not enjoyable like this...
I tried my hardest to get it to run smoothly, but it looks like something is wrong with Construct because it is herky, jerky like I have never seen any other app before.
Especially towards the middle of the video it gets Very very jerky...
Also, what in the world is that black bar on the bottom of the screen for? That is so annoying. Sometimes it's there and sometimes it's not (when I switch away from the app and come back, sometimes it disappears and sometimes it doesn't.) Why are there so many problems and issues with mobile export???
