I quickly played through this today to get motivation to use jcs again and I liked this pack, so I will review it :P
The levels here were designed generally well. Not terribly innovative or boundary pushing, but the quality was solid and the visuals always maintained an above average level. Most of the obstacles consist of enemies and various hurt events, with some occassional death pits. There is a great deal of story that drives this pack, which in this case improved it, because the story was written well enough (and with mostly proper english!) and because of the way it was incorporated into the levels was good. Most of the levels were fairly short, but this episode is still time consuming (took me maybe an hour to play & win it) because of the non-linearity of some of the levels and the difficulty.
However, there’s a couple of things I noticed that bothered me and lowered the rating of this somewhat. Maybe I just don’t play JJ2 often enough and I suck at it, but I found these levels quite difficult to beat fairly. After a couple of game overs I just resorted to cheating or running through parts that bothered me. Early on, the enemy placement bugged me a lot, especially because bats would often be placed in narrow corridors hidden behind foreground scenery, or would blend in to the scenery way too well in the dark diamondus B night level. Sometimes hurt events were placed quite liberally, especially in areas that would be revisited later, and in combination with the regenerating enemies (which I didn’t mind too much, usually I hate them) made it really tedious to navigate and beat certain levels. I think this could’ve benefitted from more free health lying around.
Also, some of the levels I felt were too short. It’s a good thing that I liked them enough to wish that they were longer, but they definately could’ve used more obstacles and creativity to make them longer and more memorable. I liked the non-linearity of some of the levels a lot, but I felt that maybe it wasn’t used to its full potential (there were some pointless dead ends, and some non-linear levels required you to visit most or all the areas anyways or go through them in a linear fashion). However, it was really nice and I felt sort of appreciative of when a non-linear level would be thrown in after a series of linear point a -> point b levels.
Overall, the visuals and the quality of the levels warrant at least around an 8. There’s also a good story and multiple levels to back it up. Only the drawbacks I mentioned above prevent me from giving that rating. This was fun to play and I recommend downloading it
