I feel like a really fun part of cake wars is always having something new, like wool walls and deploy platforms. Every time something new is added, you find new strategies, like that annoying suffocation thing I always do because I am a noob. Therefore I think lava and water buckets should be added, because it would open up windows for many more strategies. But then again, it could be a complete bust and break the game. I just think it would be a fun experiment for the game.
