I think a registration feature would be nice; then you could play the game across many devices. Also, I hope that in the future (once this becomes larger), a way to earn money from this would be really cool; maybe a non-competitive gamemode and a competitive gamemode that gets reset every 2 days or so, and the top few people within that period of that would get paid? Just an idea; you get the point.

Anyways, great game! I thoroughly enjoy it.
