I played it all the way through to find all the mines and I think they were all well hidden and diverse. Very original! I was partially confused by the fact that I could move the godot logo around in the credits and spent a few minutes trying to figure out what that was for, but didn't end up being a mine apparently. I would totally add easter eggs to the game, especially the console/internet part, I wanna be rickrolled :)
Great game!
