Thank you very much for playing, for the feedback, and for this opportunity with a new feedback jam.
Wanting to create a quick prototype for the jam and due to a lack of ideas for mechanics, I decided to create only 9 levels and simplify the UI with a 'Next' button and no button to go back to the menu.
My plan after the jam is to make a downloadable demo with objectives for each level since it's difficult for me to do that in an HTML version.
