Shabby? No sir :D
Looking good so far dude! Considering there are only 2 available levels to play in this BETA, it's very entertaining to say the least. I for one didn't find any bugs, and I really liked how expansive it was in terms of the actionscripting with the controls and all... I can really appreciate the extra effort taken to make moves possible like the running jump + kick, and being able to throw the planks by pressing S after you've picked them up.
The sprite graphics look pretty good, but may be just a tad smaller... a further 10% zoom would make it look really neat I think.
It was good to see that you tried to add a bit of humor in there, by adding the comments down the bottom from the 'players', but it didn't really work out i feel, as they take up a bit of the screen space, and you don't really get a chance to read them when you're playing :P
Anyways, everything looks very good thus far, very entertaining.
Study for your exams, and get straight back into this after, I look forward to seeing a more complete version of it :D
