Simple and easy to understand gameplay! I will say I don't think having the spacebar as a speed ability is necessary, I found myself just constantly holding it down. I'd either make that speed permanent, or have some sort of limit on the amount of dashes you get. Also the solid blue background could be disorienting at times when you have eaten everything in that area. Maybe add elements in the far background to give players a better frame of reference for where they are? You could also try a wider field of view. Other than that a solid game I enjoyed :) Definitely reminded me of hungry sharks!
