A game about columns. And gems. But certainly not columns of gems.
What kind of game would that be, anyways? Doesn't really make sense.
Controls: Arrow keys or WASD. You can double jump, even after walking off a column.
Collect gems and deposit them in the green checkpoint columns. Get enough gems to unlock triple jump!
Press R to restart and get a new level, M to toggle mute, F to go fullscreen.
P.S. You can Mario. Ceci n'est pas une pipe. (Ceci est soit une colonne ou un canon.)
