The contrast is definitely an issue. I made the mistake of not applying the background tilemap until about 20 minutes before I submitted the game, and so only during my final playtests did I realize how bad the visibility of the drones were. Thanks for the feedback!
Looks cool, I'll definitely have to try it out tomorrow! I also tried a third game called Super Window Dig which also used the window in a unique way, and I enjoyed it a lot.
