This game is very good but I do have some nitpicks about this game.
Pros. This game looks beautiful I love the pixel art it's amazing, The music is pretty nice to listen to, The concept of this is awesome I haven't seen something like this before.
Now the Cons.
I wish the little thing at the bottom was a bit bigger or you could be able to adjust the size of it in the options, In the tutorial it took me a few minutes to learn the controls because the signs didn't explain it enough so maybe some words on the signs would be cool, the last one I think would be a good addition would be WASD support and if you add wasd you could make KL the jump and dash buttons.
But again these are just nitpicks about the game I really do like this game and I wish this game gets the popularity it deserves.
