I love this game! Already on the boss of the 4th world and the challenge is great (Thanks for the infinite lives option tho, I would NOT be this far in without it)
Only complaint so far is the fact that Flats' stomp attack has barely any room for error, it's impossible to dodge the falling debris without taking one hit most the time.
Apart from that, references are all on point, art is just great, and the music is nothing short of perfect!! I sincerely commend you for your excelent game design and accuracy to the NES limits and to what a Hummer Team game looks and sounds like
