Thanks for the feedback. You can skip the intro using the Return key (the option was there, but I forgot to add the text telling the player they could do that, which has now been fixed).
Can I ask- what is it about the platforming that feels bad? Too fast/slow? Too heavy/light? Perhaps it is just dissimilar to platformers you're used to (I know different ones have different feels)? Honestly, I'm not used to platforming with a keyboard so it naturally feels a little off to me anyway. Would like to hear some more specific feedback so I can work on it, especially if others find the same problem
