Very cool game! Generally think it's a winner. I think the only thing I'm missing is maybe checkpoints where the difficulty ramps up, maybe speed increase and/or more obstacles. Also (small point), because of how slow the depth amount rises, it feels like the submarine is really small! Maybe if this increased faster then it would give a cool feeling of depth. Either way, thought this was a really good entry, got to about 33m. Good job!

Simple concept executed well! the snaking rope adds a lot to the feel of it. I gotta ask, is the sub a few centimeters in height? because those are the longest meters I've ever seen xD

Fun game! Well done
