Before I got the Badge of the day, I completed the final level in a big explosion. 100x Floes + 100x mines. It wasn't much though, all I got was a big white screen that lasted for about a minute :/
A multiplayer feature could be interesting. There could be like 4 players in one big map, with the undead also being playable. (I don't know if the undead are actually playable in this game, sense I haven't gotten so far yet).
