Well, this time I found quite a few things. Graphics made gameplay more simple and not less interesting, visually beautiful too. Though I still can't intuitively understand sound cues that radar gives me
As to bugs - I found two. I'm playing linux version
First is that sometimes I get stuck in terrain. My guess is, it is most likely to happen after bumping on high speed, or in narrow tube sections. To get myself out of there I can press movement buttons and jiggle out (or teleport - kinda frustrating though)
Second - sound sometimes crashes. While jiggling inside terrain I may get crackles in my headphones (as if sounds were overlaying and causing membrane to go insane, maybe?). And more crucial situation - like 4 times out of 60, after I heard new treasure, sound started crackling severely and completely died off in few seconds. But after collecting the treasure it returned to normal. And I hadn't been noticing such behavior of my soundcard or headphones before
Overall, I see that You shifted focus to graphics, and - for me - it made game much more playable. I've played it for a few hours, and now the main thing holding me back from returning is lack of content. I, personally, think, that it won't hurt any game to develop it's plot. There is already an interesting collection of mysterious treasures - and I need to arrange them so that they are telling stories. Also, water surface is kinda empty, and that kinda undermines whole point of "surface" part of the game, so if You could make use of it, it would make game feel more complete
