Super fun from the start.
I really like the simple line artstyle you got going and the sprites are so clean even when rotating :o
And the mouse only gameplay makes for some nice and smooth intuitive controls, just point and eat XD plus once you get a few stages of evolution the game picks up quite a pace if you manage to upgrade your speed, the overall ambiance be it the music and the artstyle also gives a very chill vibe to the game.
can't really say more about this one, solid entry, congrats :)
