Game could use more balance and gets very repetitive. Once you get the hang of it, you completely steam roll and will never take damage. There should be some kind of random chance/pressure that some of your buildings get removed or something else to manage. Maybe you have to convince your evil boss for more funds to develop the maze and that is abstracted out into a mini game of some kind. The user interface could be improved to have more feedback and also you could make use of the large empty spaces to give players tips/instructions if that ever becomes necessary. I did like having to bounce between the rooms and manage the cooldowns that was fun. The art was also good.
