The biggest thing to work on is movement first, to make a better movement add physics/behaviours like gravity, max speed, and change the friction to lower or non at all. You can view the deck I have pinned for reference. Second is animation and quality, after movement is done try to make more developed drawings and try to make animations. Third is the look of the map, make it look nice and try to theme it, the easiest way is to make a base drawing of the walls then add different type of drawings and ADD SHADING. While this is probably confusing you can look at my pinned deck to see what I mean. Good luck twin

the game is obviously a work in progress but id like to see you guys giving me suggestions on how to make my deck better
