A disappointment...
You play this game for the environment and the story. The richness of the dark atmosphere. And that part is written...decently. Spelling mistakes abound. The "haha"s are jarring visually to see along with the rest of the text. Just take out the " "s. I'd recommend finding an editor to double check your script. Finally, the text moves at a snail's pace and loops itself. So I sit there in a level that takes 5 seconds to beat, reading lines that I can read in 4 seconds, waiting for words to appear that take a minute to show up, but I still stuck with the reading the story because it was interesting! Your story can shine if you learned a bit more in flash to make this run smoother.
Next is the glitches. I played the last installment, Heat, and I had to stop playing because I got caught in a brick. I watched the rest of the game on youtube and started playing this one. Right before the end, I got caught in another glitch.
~~~~Spoiler, look away now.~~~~~
When I was fighting Light and right after he flashes back to the accident, I went into a jump and got stuck on something in the environment. What happened in those levels would be some sort of random shift of all the blocks. It would then land over heat and It started to crash my flash, so I had to shut it down. This game is loads more advanced than Heat, but if you still have technical problems with your game it'll prevent people from missing out the ends of the story.
I reloaded the game and tried it again. Then Heat wouldn't stop running left for some reason.
I tried it a third time and ran till the end. I did this mostly to check to see if you used credits, and you didn't. Some of the art in there wasn't yours. It was ripped off of the Madoka Anime. Please try to include some note about that in the future.
