I like the main idea at work here. the idea of sneaking around, managing your color and trying to be stealthy is neat. But I think multiplayer is all about communication. It's not clear who's winning or what winning is -- is my goal to kill, or to get collectibles? How much green do I have left when I use it? It's really hard to judge what's going on without that stuff (an ugly text box is totally fine for this level prototype). I kind of want semi-obscured transitional areas where I can change my color (like there is a wall in the foreground that I can go in front of, so I'm not guaranteed to be half the wrong color when I go from one room to the next). It might partly be the UI, but I'm not really feeling the resource aspect of this. It does seem like I run out of each one, but they still kind of just feel like regular old resources in that regard.
