Hey, thanks for playing and sharing your feedback!
I see the suggestion of controlling all crabs in one go is a recurring one. I didn't want to implement that initially, since I want to emphasize on control of crab's positions against each other, and also convey this feeling of actually issuing commands. I have some UI planned specifically for that, and I even though of introducing a cooldown for commands - to require player to be more strategic with commands and avoid click-spamming micro. But, if that approach fails, I'll definitely consider adding group control! The feedback is invaluable in any case to better understand this issue and move the game in the right direction.
