What a neat game, love the presentation, and the fact it's not just a style and can be run on an actual Game Boy adds a lot of authenticity. A little nitpick is monochrome green palette in the style of original GB would've been easier on the eyes.
The puzzles seemed too easy at first, but later ones actually took a bit of time to figure out. Couldn't complete the last level, though, it's seems my solution (which should work - all bots are standing on the platforms) is not the correct one, had this problem with one of the previous levels too, wish there were more than one solution.
Nonetheless, it's definitely one of the best entries, well done.
