Well, thanks for the feedback, this is my first game jam and I was only able to complete like 20 - 30% of the gameplay and at the end of the day I just put the platforms anywhere(not a good designer) and made small win logic. I mainly focused on the character's mechanics and didn't think about the other aspects like graphic settings and all. Sorry for the bad experience you are facing due to graphics, from now on i will definitely add the graphic settings.
