Grinding is, i think per definition, the task of repetitively doing a certain (and oftentimes completely boring and skilless) task, to achieve a goal (gathering money, items) without actually playing the game, but still is required to progress.
What you described is playing the game, not grinding. If you have extensive grinds in your game, you probably designed it wrong.
For the megaman part, yeah, i love the intro stage. It's awesome and i could gush about it almost as much as egoraptor, it aswell makes, if i may, my dick rock hard
The dumb-downness, or overtutorialization, or whatever you wanna call it is really driving me insane. especially if unskippable and presented in a really awkward and annoying fashion (extensive dialogs to bring across a simple point).
Text like "press jump to jump" doesnt really help either. Sure, with the keyboard you have a bunch of available buttons to press, but you might aswell show your players what keys are bound in the menu/options screen, or, god forbid, have a control config (it's not so hard to do, come on people).
