Incredible game! I think the only thing missing are online leaderboards. If you want an could host them for you. :D
Other than there is nothing I can criticize - the game mechanic is super fun, and the polish is next level. Seeing the new environments is really motivating and the effects when destroying blocks and building combos are insanely rewarding!
I have a simple firebase project set up, if you want I can add an API endpoint for you that you can use to upload and download scores. You game is sick so I would love to contribute! And it would only take me an hour or so. I used it for quite a few projects before (including this jam) so I mostly got the hang of it by now. ;p
You can add me on discord if you like (username: bene_labs) and I can guide you
