1. When Toby jumps while overlapping the tutorial shield, everytime the tutorial text appear. To avoid this it is better that Toby has to left this short area and if the player wants he could collide with this shield again, bevor he walks away.
Why you don't store every tutorial text, when touching this shield the first time. So i can everytime read these tutorials? I don't know how many tutorials you have.
2. Jumping on snales: snales are like trampolines is this really gameplayelement? Without touching controls he jumps and jumps and jumps over again.
Your touchcontrols could be better.
When a enemy is on the ground i can't see it because of my thumbs
When the touchfield are vertical planes i can choose where i wanna touch it and it is more comfortable.
