I really wanted to leave quality feedback here, but my keyboard is weird and combines the arrow keys with the WASD keys, so it was impossible to play using those controls. :(
However, what I did see was amazing. The music was great and fitting for both the hard-working industrial setting and 8-bit design of the game. The art was really cool too, and knocking your boss off the edge is a genius way to combine both the requirement and theme. Overall, it looks like you put a lot of effort into this game, and I'm really sorry that I can't play through it all.
