thanks for trying it out :)
the dialogue has been adjusted to speed up text X5 if the player tries to advance early with A, sort of a 'skip'. I will work on fixing the text box inputs for keyboard.
chaining jumps is intentional, at least the crouch jump/super jump. there are multiple ways to execute the jump but the crouch+A is the easiest for beginning.
I will definitely work on getting some sort of visibility resolved for when the player is behind objects.
Also if you have a way that I could attempt to recreate the momentum issue you are having, I will be willing to work on it. The character is meant to feel a bit heavy, but if floaty gravity and smooth momentum should work better I can always try it
