I didn't have the money bug, but if I did I would have given you much fewer than 3.5 stars. I did have a bug where I paused during a run and clicked into a new tab. When I returned, it showed the whole 'click here to resume' thing on top of the pause menu because I had clicked away. I clicked to resume, and my character started running again even though the pause menu was still over the screen!
I kind of like the stuff it does to my eyes - the verticalness doesn't bother me.
Someone commented that there's no warning when the lycan upgrade wears out. I don't know if you only just very recently added the wolf howl pause to indicate the change back, but I have it in my game and it works really well.
I enjoy the multitasking and while I feel like I'm getting much better, I still haven't seen a boss which is a little disheartening!
