I'm working on it, but I ran into a bit of a snag... While modifying Level 2, I noticed an error: all the blocks had a height of 3.5 instead of 4, so I basically (almost) had to rebuild the level from scratch. This fix will be included in your build, but I also had to fix it in my main build. I expect it to be ready in a few days, as long as I don't get too bogged down with other stuff.
Edit: I also modified the walk/run speed in levels 2 and 3 to match the original game.
