I love what you were able to do with just a cube as a player character!
Wish I had more time on my hands so I could beat the game. An extra checkpoint or two would have been nice for this, haha.
Regarding feedback, I was gonna say I really wish you could jump higher but right when it started bothering me I found the double jump. A slightly higher jump for more forgiveness would have still been welcome but also likely just a skill issue on my part. The camera is also a bit finicky when it moves and jumps around to the next segment.
Otherwise, lovely game!
