Fun game and unique concept, but I feel like there isn't too much challenge involved, the red blocks move at a pretty small speed, and once you figure out how to keep the blue blocks from being flung out from your person because of the movement, you can just kite the red squares and since the blocks dont appear to have damage falloff, it is easy to build up a large stack of blue squares and survive that way. I think implementing a scaling system for health and speed, or introducing new types of enemies would improve this game a lot!
