Nice game, i think this one reminds me on playing minesweeper kind of thing so it's really cool! The art is simple but good the music is nice especially the elevator sfx, it is a great touch. The tutorial really helped me out understanding the game so no problem on gameplay, however it would be better if the elevator changing floor is using keyboard and not mouse or use WASD for movement, kinda hard transition between the arrow key and mouse. Other than that, it is a solid game, great job!
