Kingdom Rush ReVengeance - Treasure Island Campaign (Impossible)

I can't believe we are already at the final boss of the final campaign, these last just months flew by and ReVengeance was truly a blast to play on impossible difficulty. I really like the premise of the final boss. This is the first time in the franchise they've brought an old boss back (unless you count Malicia and Spider Goddess as one) and having to defeat all of the previous bosses again added a lot of excitement to this level. New paths appearing throughout the level was also a welcome surprise the first time I played it. However, the final stage was somewhat of a disappointment in terms of difficulty. Sure you have 5 bosses (2 of which permanently destroys towers) and a parrot which constantly steals excess gold, but you get so much gold anyways, that none of that matters. You can argue that I was using meta towers and a hero here, but this was still the 2nd easiest campaign level in Pirate Kings (after Monkey Island), Sharkpool Reef felt like a final boss level more than this one did. I still found it fun though and it was a cool end to the game.
