Nostalgic
Things like this were my first contact with electronic entertainment, although in my country we didn't have original Nintendo games, only Russian copies.
You did a great job evoking the feel of these old games. The game itself bored me very quickly, but that's just me being spoiled by more complicated games throughout the years. Mixing GoW with Game&Watch was a fun idea in itself. I'm giving you 10/10 for idea and for letting me reminisce ;)
