This was fun and interesting. My first failure though - I'm glad you included the radioactive hints on the chest graphic because I initially thought it was a treasure chest.... XD
I would say that it does seem kind of like the rope is cosmetic only, but that's fine.
Was glad the music was included, kind of lightened it up/made it flow along nicely. I don't feel like the logs are too slow, but it's really hard to get from bottom to top in time to avoid when there are two obstacles XD Kind of like a "we're doomed!" outcome.
But yeah overall good job! Thanks for the experience. Cheers.
