It was fun!

Not sure if this is expected but, after throwing an object against the wall, I'm able to pick it up again, throw it again and keep gaining altitude. I didn't make past the "reversal" part, sadly.

Gotta admit I had a mild freakout when I saw a .exe inside the Linux package ^^

That was fun!  Too bad there aren't more levels.  It felt like it could be a really good fast-paced platformer.

Nice graphics and a very good and interesting mechanic. I was a bit confused with whether I was supposed to click the left MB once to pick up a box and then click it again to release it, or if i was supposed to hold the left MB pressed while holding it and the release the button to release the box. Both ways worked, but the latter version worked with the most precision.

Loved the trail left behind the chicken and how throwing down the box made the chicken jump higher. Wasn't the clearest in the 2nd level about throwing down an object to make the jump but I figured it out - I thought I would move the box and jump from the top of it. Maybe have the text about that from a later level put there earlier? Also, I was pretty impressed with the slomo too.
