Playing as Proto Man made me turn on this game. Taking double damage while not having the ability to buy more lives or E-tanks is too rough a challenge. The annoying boss in Wily's Stages really stood out with how hard the game is.

I used the Collection's save features to get through this game– saving up lives and E-tanks for the finale– and even then it was still rough. I wonder how tough it's going to be to finish MM10 with Proto Man?

EDIT: Looked it up and I already beat MM10 with Proto Man and I bet it wasn't nearly as difficult as this one!
