The yellow and the orange are very similar and I had a whole moment when starting of toggling my colors trying to find blue for the yellow creature. However, I figured it out and started to really like it. I think the random start spawn is creative, but I had a harder time when enemies would spawn right next to the player. I think instead of this, increasing wave amount might be a better way to make it difficult for the player. Overall, this was a fun game and easy to get into.
