Point builder

Hello all, I am looking for some advice on a course I am building.

I want people to navigate a scenario and depending on their choices they can be penalised by gaining penalty points. 

Is it possible to do this?

so, if they take the incorrect route they gain points and the highest points lose. I would ideally like them to be able to see their accumulated points on their screen as well. 

Can anyone  help? 

Thanks in advance
