Thank you for your feedback.
Yes, there is some visual art that was meant to be added in the last day (but due to our limited time to make this project, we rather had to focus on making it playable, fixing bugs, etc).
You got that right, about the robots: our original intention was equiping the Robots with some kind of Electrostatic Gun (very much like a Taser...) to stun any enemies 1 or 2 mtrs in front of them. With that in mind, the enemies would also be able to shoot you with a similar weapon (making you loose time and health), instead of just 'being in the middle' to make you waste time. But again... those ideas had to be put away for a next version of the game because of our time availability for this Game Jam.
We are definitely going to make a more polished version of this game, with all those ideas and some real art.
Thank you again for taking the time to play our game!
