Hammerin' Harry is a pretty simple platformer. Armed with a big hammer, you make your way through 5 levels, and the first 3 levels have bonus levels as well. At the end of each level there is a boss, and in some levels, there are also mini-bosses. In short, this game is a "normal" platformer, you won't have a hard time figuring out what's going on.
Bloopiero improves on the previous movie by 00:12.91 thanks to many new tricks and skips, boss fights done in half the time, and major lag reduction.
