A good submission that meets the requirements of the brief comfortably, the visuals and soundtrack are of a good quality and the game is forgiving, which would be appreciated by a hyper-casual audience.
I do feel like the game can feel a bit sluggish and the game doesn't progress in difficulty, or if it does it takes a long time to do so. In addition, there are no upper boundaries so you can spam left click and fly off screen, which would be a very simple fix. Also, is the way you have exported the game the most accessible option that you could've come up with?
That being said, the game as a whole works and can be played with little mental effort, which would be an important factor when considering the target audience for such a game. I could see the game as is, with some fixes, to be something that caters towards young children to keep engaged, which is an entirely viable market.
