I feel like adding some gravity to the game (like Flappy Bird) could open up some more tricks like driving when a column is really low on the screen, and possibly adding some scoring system whenever you pass by a column. (Lol kinda like Flappy Bird but learning to do these features could be helpful for other games as well). Would love some visuals to it as free assets would be fine as placeholders.
Though it was enjoyable and great you figured out how to have it infinitely generate from the left!
