There is an ending for Ginny. You have to build a certain relationship with her, (talk to her in the cafe every time you can) and not die too often. (best achieved on normal)
Part 4: keep your mouse near the top as much as you can, and you can keep the mouse in one place for a while without losing a life, just watch out. When it starts getting too hot where you are move to the other side of the screen. Watch out for little circles falling from above. Part 5: start at the bottom left or bottom right and make a square on the screen with your mouse around the cannon's shot. Part 6: the green worm always comes from the bottom right, so start with your mouse top left. make a circle around the edge of the screen. The worm comes back on from the same side it left the screen on. Same strategy, just be sure you're not next to his tail. Part 7: similar strategy to part 2, except you want only the mittle wall moving. When the top cannons shoot dodge to the bottom and when the bottom cannons shoot dodge to the top. Tip: the top cannons start shooting. BIGGEST TIP!! DON'T CLICK
The impossible badge isn't tooo hard. Part 1: move the mouse slowly back and forth across the screen, the cannons shoot where you are at the moment, so as long as you keep moving they won't hit you. Be careful at the edges. Part 2: As soon as the bottom wall closes, go back down. That makes only the bottom wall move. that makes it a lot less confusing. Part 3: circle around the screen with your mouse: when the top canons shoot have your mouse on the bottom, when the bottom cannons shoot, have your mouse on the top in one continuous circle. Tip: the top cannons start shooting first.
