After playing this game for about 10 minutes or so, I've found this to be a neat little concept. It's very reminiscent of those nifty time-waster games you'd get on mobile back in the day (Flappy Bird is the only example that comes to mind right now). The game does have its flaws, but hey, that's what Newgrounds judgements are for, right?
The minimalist aesthetic this game has is spot on. It works perfectly, because that's the kind of game it is: an easy, simple experience designed to be picked up and played at a moment's notice. It's kind of like a zen feeling, in a way, although I wouldn't exactly call the gameplay itself the most relaxing thing in the world.
Speaking of which, the gameplay is simple, just like the aesthetic, although I would go as far to say it's *too* simple. While being limited to a single direction helps keep the gameplay as minimalistic as possible, this also means that all of the levels have to be built around this concept (i.e. there must always be an opportunity to turn right). This simply isn't the case, as can be best seen in Level 4. Sometimes the dots will appear right in the middle of the bottom/top intersections, making it almost impossible to turn right in time. Not to mention the fact that a dot will sometimes generate in the bottom-left corner, which makes it literally impossible to collect without dying. There are two ways to solve this problem: redo the levels so that a right turn is available to the player at all times, or allow the player to turn left (my personal suggestion is to have the left half of the screen turn you left, and vice versa). I've also found it a bit hard to judge the distance between myself and the corners due to the slight 3D perspective of the levels, although this could just be me.
As for the scoring, if getting the highest score is the main objective of the game, I personally think it would be a lot more fun and challenging for the player if the scores were kept for each individual level rather than for the whole game, as this would encourage the player to play different levels, and not just stick with the one they know it's easier to get a higher score on.
Apart from the issues mentioned above, I do believe this is a concept with potential. As I mentioned in the beginning, this is the type of game that reminds me a lot of the stuff you'd get on mobile devices; have you considered making this into an iOS/Android app?
