Ischa has released a pack called The Three Seasons. Before we get into the review, I would like to suggest providing the links or telling us where to find the music. OK, now for the review:
SUMMER FOREST:
I thought the eyecandy in this level was OK. Not great though. There weren’t any problems with the eyecandy, no bugs or mask problems. However, there weren’t any particular parts of the level that were exciting or significant. Not much to say about the eyecandy, except that it was good, but not great.
The gameplay…well, there wasn’t really a lot of gameplay in the level. There were not enough enemies to make the level harder. The were only blocks used in the level. There was one trigger event, and all that was used for is getting the only type of ammo in the entire level. There wasn’t really anything to stand in the way, except some very easy obstacles. You reach the boss at the end, but if you die, you must start the level all over again, which is fustraiting. The boss its self was made harder by those funny freeze things, which is good because Bubba is a prety easy boss. There was also a Fall down and die obstacle which is one of the most fustraiting obstacles, especially when you have to type JJK.
LEVEL RATING: 5.7
AUTUMN SWAMPS:
The eyecandy is pretty much the smae in this level. No bugs, but nothing special either, except one bit of the level, where you have to be spaz and then you find yourself running along a very long branch. That banch, however, was the most appealing of all the branches of JJ2.
The gameplay in the last level was empty, but this level is even emptier. There were even less enemies and even less ammo. There were some little wind obstacles, but they were quite easy. There area couple of parts where you have to morph characters. Overall, this level was emptier.
LEVEL RATING: 5.1
WINTER GLACIER:
The eyecandy, again, was boring. OK but nothing special.
The gameplay was alot better than the previous levels. Especially at the beginning. There were more enemies, the level was alot harder and there was a nice trigger puzzle. However, there was less ammo than before and it was the most usless kind, freezing ammo. Also, the end boss may have a bug because it took a long time to appear when I got to the end, and it suddenly appeared in the middle of the level and started attacking.
LEVEL RATING: 6.4
OTHER THINGS:
Yes. Another point is that the levels were all very short. I feel that if they were longer, more gemplay could have been included. I would decrease the rating, but because of the lack of gameplay, that may have already been achived.
AVERAGE RATING: 5.7
RANK: 5 Average
DOWNLOAD: They were some average levels, but there wasn’t really anything special in the pack.
