Nice one! I Hope you learnt a lot on this 3 hours ^^. Some quick suggestion for a better jump feeling, if you have a rigidbody2D (I think you do). Increase the gravity affecting it and also increase the jump force you are applying. A common time for a good feeling jump is to stay in the air around 0.7 seconds. So mess with the gravity force and with your jump force to try to get that :D. And add the force as ForceMode2D.Impulse
Please don't get me wrong, I don't want to look clever or something but those small tips were incredible ones for me when I started developing! GJ overall!
While I do have several years of experience with Unity, I believe this is the first time I worked with 2D physics (Not the first 2D by far… but I just don’t like physics .-.). So, thank you for the insight!
Every small bit counts, because in the big picture, it’s the small things that pull us through.
