Hey, played this level set the other day and thoroughly enjoyed it. It didn't seem too impossible and always felt relatively beatable. I haven't finished it yet, but the only level I gave up on was level three; t'was a bit too long for its own good.
Also, I'm pretty sure the version I played was slightly different. In level two, I don't remember seeing the tri-saw-blade at the beginning; I didn't have to jump and fall through the chute you created, I simply went under the saw blade altogether. Don't know if that was an updated or out of date level, or just me.
Anyways, great chapter thus far.
