Damn. So first of all, I was up to 46k points at the end of level 4. I accidentally cleared a few levels and rode it out til round 2 and cranked out some more points.
I didn't realize how fast this game gets! I took some risks on 2-1 and 3-1 but pretty much played it safe otherwise. Around the middle of round 4 seems to be where most people screw up.
In round 4-5 I think I took what seemed like a reasonable risk (something like a 5-line with a yoshi) and just flubbed the rest. That kind of thing where you plan a line, only to have the next row spawn without the piece you need.
Might try again later, maybe not. But this game's a lot of fun. Although I think I'd have more fun just playing to see how far I can get instead of a high score
