Audio is a tough one to get right, that's why I have the +/- to set the volume. I have people both tell me it's too quiet and too loud.
I suppose for the bomb one, it could be a fault if you don't throw it across the line.
I actually liked the knife throwing one. It was meant as a break between the button smashing because you only have to aim and then throw the knife at the right time.
For the running, I matched how it was in the original, because I thought it was fine, each button is its own little distinct speed up, but you could mash only one and make it through. So you could alternate, or just mash each asynchronously, or at the same time, however you feel most comfortable to button mash.
Leaderboards seem to be popular, I guess since it's pretty minor to get one up and going I should start working on an implementation I can copy pasta into different projects.
Thanks for the feedback and thanks for playing.
