My colleague Thomas Davie was playing with your Tetris game, and it seemed that it contained a space leak; it was consuming more memory, slowly.<div><div><br></div><div>Could it be caused by the top level </div><div><br></div>
<div><span class="Apple-style-span" style="font-size: large;"><span class="Apple-style-span" style="font-family: 'courier new', monospace;">testTicks :: Event () </span></span><div><span class="Apple-style-span" style="font-size: large;"><span class="Apple-style-span" style="font-family: 'courier new', monospace;">testTicks = levelToTicks 1</span></span></div>
<div><span class="Apple-style-span" style="font-family: 'courier new'; font-size: 16px;"><br></span></div><div>I'm not sure how Events are implemented in Reactive, but in a classical FRP setting the "heads" of this top level variable would never get garbage collected.<br>

Hey Reactive,<br>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.<br><br>A few caveats:<br><br>This code is still _really_ ugly, but it does work as far as I've tested<br>
There is no game over, you need to quit manually<br>There is no score or level adjustment yet. I need to add that when I have more time, i.e. after this week<br><br>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.<br>
<br>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.<br>
