Tricky little game! I included it in part 2 of my A Game By Its Cover 2015 compilation video series, if you would like to take a look :) https://youtu.be/HjQhuyKvNzU

This is really fun! I haven't gotten very far yet, but it's a really fun concept, and it plays quite well! Lots of brain bending. :) I was happy it was playable with a mouse, though, because I can imagine exactly how you would play on an NES, and moving a little cursor over every space in the grid wouldn't be quite as quick.

Congrats on finishing so fast! :D
