In addition to introvert mode suggested above, there could be a monogamy mode where you have to stay with One square as long as possible without ever spending too much time with a second square.
Love the game, but I wish that the classes were more different. In vertical drop, I really feel like the game play is different for each class. In this game, some of the classes are better, but none really require a different strategy or gameplay. But great design, as always.
I think it's silly the way the turn order works. Killing a weak bug early on just means the stronger bugs will attack you more often. The big bugs shouldn't get to attack more frequently just because you're destroying their allies.
Very slow. And instant death makes this sort of boring for me. Consider systems like katamari damaci where you don't instantly die (on most levels) just because you hit something bigger or roughly equivalent in size.
I do like the idea of gravity in this type of game though.
Odd vocabulary, no way to boot people who just write out the words, no alerts when you get words close to the answer or singular/plural, annoying inability to draw on entire canvas. All in all, worse than isketch in every way imaginable. And it's an ad.
I like the loose camera and cartoony aesthetics (and monocle). It reminds me of worms but maybe a little prettier. Good job putting a fun little game together.
