I guess using your memory is part of the gameplay, but having the ability to see what robots have been deployed already could be quite convenient to keep track of them, as sometimes it could get a bit overwhelming. Nice art and UI!
Memorising weapons used was my initial idea on making it challenging but I agree entirely about giving the player more feedback on bots already deployed. I intend to put something in for the player to track this kind of thing. Thanks for the great feedback!
