Nice game! I liked the art style, it was fun, and it was pretty challenging.
The sound effects were good, but there just wasn't enough. The enemies' sounds for dying and discovering the player are the same. I once thought that another robot had discovered me when it was actually just the death sound of the one I had killed :)
It would have been nice if there were some sounds for footsteps and doors.
There were a few bugs. There was a set of double doors where I could only open the left one.
There were one or two times where enemies were walking next to walls and the walls were rendering in front of them, making it look like they were half underneath the wall (I'm not sure if I explained that well, but it probably has something to do with the z index of the sprites)
One last thing I wanted to mention. I found it strange that enemies would detect me even if I was in a completely different room. Sometimes enemies would see me even if the room I was in wasn't adjacent to the room they were in.
Overall, this was a very well made game! Thanks for submitting!
