Very nice game! Entertained me for an hour before I accidentally left the page. But not before reaching ~30M points - and my two giant forests weren't even connected yet! :D
Some small improvements that I think could be nice:
- start from the smaller numbers to the bigger ones. it's really boring to watch the single digit numbers tick up from random tiny fields after you already did a massive combo.
- a big combo / the thing that clears the requirement should come with more fanfare :D
- being able to get rid of dominos could be nice - but also massively overpowered.
