The art is super quite and I love the robot, the gameplay also is quite engaging. Lack of tutorial definitely hurts, also know where the enemies will come from when you are building up would have helped. Last feedback would be the collision between enemies and the player, I had a few times that I just got stuck between enemies or the wall and an enemy and couldn't get out which was really frustrating. But I do really like what you managed to make and would love to see it grow!
