Very interesting. But I recommend that you upload the project not only in APK format, but also the WEB version. :) The fact that you are students and made a game together, it's very cool! I wish I could have done that...
I played around with an interesting idea. You need to finish the menu and make the PC version. Make a game menu.
Dilute the music and diversify the levels with uniqueness (visually). For example, on another level one design, on the second level another. Generally cool!:)
