This is a well made to play as it is visually striking, paired with great music to just vibe out to.
Although already great as a relaxing escape into the unknown, it would benefit as a game to have some difficulty curve by increasing the rate obstacles spawn in over time, and some performance feedback by having the player's current score integrated into the UI.
This game is also a great candidate for 'Zen' mode; no obstacles, no score, just tunes and dunes.
Beautiful game. Well done, and good luck! :D
