Nice game, but too unforgiving on boss stages.
GB style graphics and original music are great and add a lot of quality to the game (although I'm still wondering why "Melee" man uses a gun). For a game made in a week, this is amazing.
It's actually possible to go through the whole game with 0 deaths until the very last boss, which is almost impossible to beat. Takes a lot of tries and also luck to beat it. Just going slow, killing everything dangerous and timing jumps on cannonballs to avoid receiving damage.
