Ended up with a score of 19500ish (before getting stuck) in regular mode, 50000 (before getting bored) in turbo mode. Reasonably fun, but can't see myself playing more of it.
Games praising me constantly gets on my nerves, so changed from English to a language I don't understand. Changing language in the menu while the game is running doesn't seem to work, so had to restart to do that.
The way passing multiples of 5000 points resets your pieces (I ended up referring to the block shapes as "pieces". It's not really a good name for them.) is theoretically neat. One time I was in a bad position and placed pieces hoping to get enough points to get rid of my last piece. But often it just trips me up / is annoying because I have plans for the rest of my pieces.
Maybe it should give you something else instead of clearing your pieces , e.g. give you a piece with special powers. You just placed a piece, so it's guaranteed that one of your three slots for a piece will be empty.
