It looks awesome! It's also a good thing that I watched your video first before playing it, otherwise I would have asked myself many questions like "Why am I stuck in the middle of the level and where the hell are those "!" crates. :D By the way, putting the Crystal in the Bonus Round was really unique!
Not bad mod but there are mistake first the crystal always found in the normal route never found in bonus rounds route or secret route . Second the second gem always found in the secret route or in the end of the normal route after you doing some special tasks like win the level before timer is out and you got the other gem.
