The concept is pretty intriguing, with an interesting combo of different game genres. It can get a bit overwhelming for people who haven’t played Tetris before or are trying to juggle two games at once. I guess that part could be streamlined a bit more to make things more cohesive.
Visually, it looks chaotic, like a retro synthwave vibe which honestly isn’t a bad thing!! Maybe toning it down just a little could help make the gameplay feel a bit clearer and stand out from the rest! Not much else to add that apart from what others have mentioned.
That said, the game’s pretty good, and I’m definitely curious to see where it goes next. Good luck!
