This platformer was originally named "Piggy Platformer", but to avoid confusion with an upcoming game, it has been renamed to "Piggy Platformer 2017". I'm sorry if this has many bugs, I've seen it myself during testing. For the most part, everything's fine. And I even made the player's falling and jumping system by myself. One month, 100 views! Thanks guys!
Leave suggestions in the comments below about what I should improve on. :) Credit to @General_Piggy678 for the help on boss attacking. I only modified a few things.
