Ultra Puzzle World
Reasons for Removal:
This hack is a bit too short to be accepted. I blew through four of your five puzzles in about seven minutes, and I'd wager you'll need about double the amount of puzzles if you want your hack to pass moderation.
This hack also reminds me of Mario's Keytastrophe a bit too much. The levels are short, have stringent time limits, and are completed when you put a key into a keyhole. Unfortunately, Mario's Keytastrophe is fifty times longer and has ExGFX, a custom soundtrack, and a plotline. Your hack does have some decent puzzles, and the concept is solid, but you'll need to expand it a lot
This is not a good-looking title screen at all, sadly. Either use the small letters to spell Ultra Puzzle World, draw your own large letters/ask someone to do it for you, or just stick with the original title screen. All three options are better than what you have now.
Keep working on this. If you can make, oh, five more puzzles, I might let this pass moderation.
