Hello, congrats on your first game jam game. You've made something quite good. You might not believe it, but behind the graphics mistakes that you will learn to improve with more experience, you show good understanding of more fundamental game design. You have an excellent wordless tutorial, and a good difficulty curve. You also made creative expansions upon the initial gameplay. The blocks falling at different speeds, and falling on top of each other, actually develop the skills of the player horizontally. For the first you need to pay attention to a new property, and for the second one get the rhythm. What one usually sees is that there is only vertical progression, where the speed/rate of block spawning increases. So that is something to be proud of. Something I do have to warn about is the background music. Repetitive music can easily irritate the player, especially one with such a strong base line that does not deviate. It really sounds like you took the intro of a song, and made that loop, especially with the last note before the loop being different. For some practical advise, don't use itch.io full screen mode for Unity WebGL games, since they don't work together. Also, you need to take the Unity WebGL border in mind well filling in the game window pixel sizes. For better discoverability, it really helps to add a thumbnail. That is something you are allowed to do after the game jam deadline, since you can change the game page and metadata. Just not the game files. Hopefully you had a lot of fun making this, and I wish you good luck on any future project.
