This hack is bad. I played through it the other day and it's just CHOCK FULL of errors. You can even access the ORIGINAL SMW levels. The hack seems to end at Chocolate Island. The last level was just annoying. There must've been more than 100 invisible Coin Blocks there.
Also, FORCING the player to go back to Yoshi is a BAD design choice. I had to go back to the same fucking checkpoint in the Vanilla Dome submap about 30+ times. [sarcasm]Oh boy, what fun that really is![/sarcasm]
I have to say that barely any of this hack can be considered Kaizo.
