Thank you for the kind feedback! There are actually 4 levels, you can just click on the 'Level Solved' screen to start the next one.
This was my first Game Jam, so I struggled prioritizing the correct things. I'll definitely add visual indicators for the controls as soon as the rating period is over to make it more accessible.
Also, the music was not made by me, so please check the credits on the game page if you liked it.
