There were no changes that would impact this I believe. Unless anyone else reports a similar thing it is probably what I will mention next.

There is a fairly rare thing that can happen where the program execution time for a specific program drops like this. There doesn't seem to be anything you can do to trigger it, but often rebooting and reloading the program, or reinstalling from the connkit can fix it. Our best guess has been that the memory alignment of something in the program might be getting loaded differently on occasion which results in a lot of "out of alignment" accesses at a low level. This can greatly impact speed as data has to be moved around first at every read of each ARM assembly command in order to be read by the processor.

We've tried to ensure this won't happen, but it is possible we are completely wrong here in the assumption. Should someone be able to come up with a repeatable way to do this I'd be super happy to hear about it.

Now it is possible however that there is something that changed. If others report a similar thing with this game I can try to investigate a bit more.
