Great overall retro aesthetic in both visuals and sound. There were a number of level design touches I enjoyed, like gradual introduction of new mechanics and blocking off the path immediately in the final level to give you free time to review and plan your strategy. Man moves a little slow but I can see how some degree of that is necessary to give the player time to change the environment in the man's path. I liked it, it gave me mario vs donkey kong nostalgia.
