I decided to play it again and ... I might have beaten your highscore by just a smidge.
By which I mean I got a score of 173040.
Small critique: It'd be nice if the highscore was a bit more prominent on the menu, just so it can be shown off easier, because I am pretty happy with that score and am sad that it's tucked away into a corner. I think the fact I got that kind of score to begin with says enough about how much I like this game, though!
