Where you get into the park? If so, you're not supposed to. If you look in the corridor you just came from after that little suprise (only suprise in the first level) then a door that was normally locked is now open.
Also, forgot all about checkpoints, I'll add some in the duplicate level.
I scrapped my second level because I didn't like it ( didn't work on it for more than ten minutes because of the first level being deleted) and I made a little mini-boss that you fight in the final room of the last level.
Here are my plans for the game levels:
Intro (Demo)
Mansion Level-A,B, and the first real boss.
Basement of Mansion Level-A,B,C, and second boss.
Sewer Level-Third boss
Abandoned Warehouse Level-A,B,C,D and fourth boss
Final Level-Confidental
You might be thinking " These levels have nothing to do with the storyline!" But they have a little secret way to link together.
