Surprisingly unforgiving for this type of game! Maybe I'm just terrible (this is very possible), but I find this quite difficult. I love how Sir Yips-A-Lot just explodes when running into an enemy, definitely caught me off guard in the best kind of way on my first death.
The one thing that confuses me a bit is the interpretation of the theme. I think the idea is that there are two dimensions to Sir Yips-A-Lot's life (jumping over enemies and saving friends), but it doesn't quite feel all the way there to me.
Overall, simple, but fun!
