Wow, this one really surprised me at how addicted I ended up getting with it! I ended up really liking the core gameplay of moving things around to form rows and make upper layers fall down, and I also liked the general goofy worm aesthetic that pervades the entire experience, including the various menus.
Having said that, my first impression of the game was really rough, and it wouldn't surprise me if a lot of players quit in confusion: I feel lucky that I stuck with it as long as I did! Could definitely use a bit better of a tutorial, as I spent way too long thinking that there was some sort of color-matching mechanic to focus on, like you'd see in games like Puyo-Puyo: the little tutorial gif made me think I was supposed to sandwich opposing colors or something, and it was a surprise to learn it was just row-clearing like Tetris!
Heck, even now, despite liking the game, I still don't know the rules fully as I sometimes get these combo/chain clears beyond just the row I'm working on that I don't know how I did: for those it would be nice if something would pop-up, like 'color-match combo +50 points' to let me know and feel good as well.
Also, I'll say that despite how goofy and energetic the game looks, it was really letting me down in the audio department due to a lack of music and sounds: could definitely use some more work there, as while some places do have music and sound, that only serves to make their absence in some spots like the title menu all the more awkward!
I also wasn't a super huge fan of the fact that you need to gamble to acquire these puzzle pieces: I don't even know what the unlocks actually are, but having to do such a mindless luck-based grind to do them isn't my cup of tea. But I'm probably in the minority for that, so you do you.
