I've been going on about Sam and Sara in a few different threads, but I decided to put a thread up for feedback now that it has been submitted.
Enjoy!
Just tried it, it works really well, definitely an addictive game! I found it slightly easier with Sam I think, as you have a tool which gets you out of a tight spot (although my best score was with Sara, so maybe I'm wrong). The little touches like the grass particles and so on make it feel quite polished and the platforming is good. I think the only thing I'd change personally is a more noticeable ghost jump after a platform, which will make it a little more forgiving. Overall great work though
