Thank you for the feedback. I will also add a tutorial level to it in the future and as ereborn suggested, I will make easier closed levels for the beginning. As the developer of the game, I used to struggle a lot with the game. Even now I struggle with level 3. I made it difficult on purpose. One thing I should have done before was to provide the instructions to use the controls in the submission feed too. I have done it now but it may be too late.
I wish you all the best for your future game development endeavors!
