More gamification needed

[rromanw]

When I play the game, I get frustrated over time that I can't manage the game anymore and the time reward is not enough. I'd be happy if there was something like tetris levels. I could track my progress that I can sustain for example level 6 indefinitely and on level 7 I can last only 2 minutes or so. Further "level up" cues would be awesome too.

Also for my purposes, I'd like to have the option to make the tiles smaller. I'm having troubles with my mouse accuracy and would like to improve it in this game.

I'm planning to add some kind of "Arcade mode" in the future that would be basically what you described.

See #112 (comment) for a new "story mode" I am planning for the game.
