Getting better, but...
I'm glad to say that I enjoyed this flash much more than the others. My biggest complaint is that there is no message telling you that you need to press space to advance the flash. But after the five or so seconds it took me to figure it out, I was fine.
You seem to have a pretty good story going, even if its has it's share of cliches. I applaud you for your solid effort. What I'm really impressed with is your improvement in grammar, I spotted significantly less mistakes!
I also found the music during the loading screen to be tasteful. The only thing that's lacking are the visual effects, I feel that they can be made a bit prettier and that it would help spice things up a lot. In conclusion, you did a fine job and I hope to see some improvements in the following installments!
Good job!
