The objectives in the game are both interesting and generally relaxing to start. Typically, I prefer a use of icons in the UI because it might be more visually appealing and easier to see for the player like hearts to show health points instead of just a number. I also like the varying environments that the player can traverse through but utilizing a better background that matches the theme instead of a grey screen would be nice. One critique is making sure the game feels fair for the player and ramping up difficulty/expectations at an appropriate rate rather than having the player die too quickly or suddenly later on.
