Flawless.

Absolutely flawless.

Uber addicting and fun.

Music is too creepy, though. I'd rather play this to something more upbeat.

Incredibly fun flash game that pokes fun of Portal. 5/5

I think it sounds just fine and dandy.
Nass job.

Less of an exploring through uncharted highlands feel...
Has more of carrying cargo to a faraway and unfamiliar land feel.
But overall it sounds jolly good and is well put together.

Absolutely brilliant, good sir! This may be my favorite track of yours!!
