Some of the levels felt like a repetition of the same thing.
When turning left or right, the main character's position seems to be way off.
The information i get when i press the I button seems to form a safe moving area; i can easily complete most of the levels by pressing the I button and moving.
In the level with the big wall, two thorns and two lava rocks, touching the wall seems to make it impossible to progress.
Congratulations on completing it.
