First, the game is not properly packaged. It should be only one button to download. Put it in a ZIP file. Also, the character is so tiny that I couldn’t see him walking and lost like… 1 minute searching and pressing all the keys.
There is no highlight in the book to convey the need to press a key to read it. The plataforming has really bad collision shapes, no animation nor rotation to walk/climb.
I was drawn by the good background art, but the game lacks many essential things.
