Thank you so much for the feedback! That's a wicked fast time!
I'll look into making switches larger and see if I can improve the interaction angle/range.
Autorun? Hmm... maybe I can add an option to switch the run button behavior: keep pressed to run or one touch on/off.
About the lag spikes... yeah it's a big problem that I still can't figure out how to solve. I'll have to keep tinkering with stuff to see if I can make the game run smoother. Also, I hope when I build it into a stand-alone distribution the spikes will decrease or stop.
