It's a very satisfying game, in the vein of flappy bird (and stuff like it).
I think that if the mouse-plane (Pink) didn't *exactly* follow the mouse - and was speed-restricted instead, this would be improved by a lot. While having the asymmetry of movement is an interesting dynamic, having Pink drag the keyboard-plane (Green) around feels a bit... infantilizing to Green. I something had the pair move forward too far, and had to backtrack with Green.
A longer camera distance would be useful to strategically plan out your moves. Sometimes I would find the next blocker too late to do anything about.
I enjoyed it very much!
