The graphics look amazing!! really nice lighting and environment, I like the 'game close' timer though I wish it was optional or had a minute grace period first (so it would countdown after a minutes break).I also love the general concept of the game and the also the the day-night cycle is a nice bit of polish for the whole game. The music is nice and calming and the replayability of the game gives geometry dash vibes :]
In terms of criticism: The jump isn't very high/far which is really annoying because the obstacles are so wide so it's very difficult to judge how far you're going to go because the speed of the run animation makes it seem like it would be further, also it's hard to see where you jump or where obstacles are because of things that come in front of the camera
Although the game has very calming music and visuals, the annoyance of the jump makes it feel like a rage game LOL but overall it's a really nice game and I like the idea a lot, maybe adding some kind of variety to the levels would be nice (unless you were going for something more like geometry dash, then dw about it)
