Hey Reactive, Since I have no hosting space I'm actually going to include the implementation as an attachment all in one file. It's not very long anyway, so it should be alright. A few caveats: This code is still _really_ ugly, but it does work as far as I've tested There is no game over, you need to quit manually There is no score or level adjustment yet. I need to add that when I have more time, i.e. after this week That being said, my first real reactive program was surprisingly simple once I got comfortable with the semantics. The actual reactive code isn't that complicated, but it did take a pretty big shift in thinking from writing explicit game loops. I've included a good bit of comments so it hopefully it isn't too hard to follow, but if there are any questions about why I did something a particular way (the answer may be 'I'm dumb') please e-mail me or find me on #haskell.
