This is actually a pretty good pack, that does have some weaker points which fortunately don’t distract from the things that make it fun.
The story in a nutshell: Devan kidnaps Eva, you travel to Devan’s castle, meanwhile Devan conquers Carrotus Castle, you return there to save the day. There’s an interesting plot twist at the end I won’t reveal here, but all in all it was a nice variation on the generic “Devan attacks world you save it”.
The pack starts with an introduction level, using still frames from the JJ2 cutscenes to introduce the story. It’s a nice idea and works well enough, but sadly the pictures suffer from colour reduction and rather MSPaint-like fuzzy edges, so it doesn’t look all that great.
The other levels all use the same tileset, presumable made by Troglobite himself. While serving its purpose of creating a world of castles and gardens, the tileset is mediocre at best and doesn’t allow for much interesting eyecandy. Still, I’m reviewing the levels here, not the tilesets, so that’s not really relevant. A disadvantage of using this one set though is that the whole pack looks rather dark and plain, and that every level looks the same. Some variety would be an improvement here.
As for the gameplay, this is obviously influenced by EvilMike’s episodes, even copying one of the puzzles (the spike bolls in Devan’s Castle) almost tile-for-tile. Most elements however are either standard stock-puzzles (exploding trigger crates with TNT, for example) or self-invented. I was particularly surprised by the “timed shot” in the Saving the Day level, which I found really clever and fun. There are a couple more such puzzles and constructs that make the levels fun to play, though sometimes they can be a bit too hard. Luckily there are plenty of carrots and extra lives, so this balances out quite well.
The level design is usually fine, though I think it is a bit “platformy” at times. Lots of small platforms just floating in the air, without much sense of an overall structure. It would be a good idea to try to design the level as a whole, and to make it really look like a castle structure-wise, instead of bit by bit.
I don’t want to spoil too much, since a great deal of the fun factor in this pack is in the surprise of yet another fun gameplay element’s introduction.
All in all this is a fairly good pack, with mediocre eyecandy and average to great leveldesign, that will certainly be enjoyable to play through. Though the levels may get boring after a while, there’s enough fun stuff in here to warrant a download recommendation.
