It's not a good idea to make a gamejam game on mobile. Chances are, few most people won't download it to their phone.
But I did. I couldn't play it because everything in this game is too small. The character is small, the buttons are small, because of this control is not comfortable and too much strain on the eyes. And also I could not jump over the first platforms, because I kept falling down. It's like there's something wrong with the length of the jump.
