What video game is this?

okay i played this one video game on a computer once but i forgot the name. okay it was really pixely, and there was a man with a hat and a breifcase ( i think ) and he had to swing over lava puddles, then he had to jump over rolling tree logs, then there was like fireballs or something i forgot. oh & there was these sacks of money he had to get i think, idk it was a while ago but thats all i remember. so yeah just tell me the name of the videogame please and i will love you forever. fanx :D
