Nice touch with the tutorial. I like that you added the ability to jump to the end of each dialog message, many games in the game that have a dialog system that types our the text doesn't implement that. I like how the player looses his hear when he dies. 8 bit audio effects or good and retro.
The physics of the player jump could be tweaked a bit though. Felt very floaty. Maybe try adding more gravity and counter balancing that with more force on the rigidBody.
Nice submission.
I'd love your thoughts on my game.
