I don't agree much with the description. Honestly, this hack was more boring than fun, mainly for the design, which is very linear. The levels this hack is made of feel like they are inspired from the original game; a bright example is the castle, which has been edited in a more boring way, without fences and the autoscroll + crusher in the second part.
Aesthetic-wise, it's okay. The author slightly edited some of the vanilla tiles, like the cement blocks. Nothing much more to say.
Overall, 2/5. The design is way too flat to be enjoyable.
