The actual plan was to make multiple environments for the levels: a factory (where the robot was created, some sort of maze, maybe something related with the city…), but I only had time to make 4 levels and it was a bit pointless to spend more time making new tilesets.
I really like the concept of this game and is something I did not think of. I would make some improvements on the UI to make it easier to control, but it is a great idea.
During the development I run into multiple problems with the projectile, so I made it if the vision of the player activates it, it would not kill you. Otherwise, it might seem to be activated by the vision but it is not.
