When I saw the title of this I thought about real boss fights. The descriptions of bosses are also fascinating and intriguing. I even hoped to see some unused villians in this pack, though you didn’t use Angel Script…
Layout is rather simple, but I liked the use of trigger zones and moving platforms in the last level.
Tilesets… I don’t like these tilesets at all. Probably overusing the original ones from JJ2 isn’t the best idea and maybe fans of JJ1 may enjoy gaming within these tilesets, but as for me the tilesets you have used are dull and annoying.
Gameplay. In fact, every level represent some kind of obstacle course instead of boss fight. There are no bosses at all! So the title is a little bit confusing. I have to admit that trigger zones are widely used, which adds some new mechanic to the common JJ2 gameplay, that’s fine.
I see that the levels are neat and tidy, whithout bad tiles, seems like they were made wisely like you aren’t a newbee in levelmaking. So I’ll try to rate as high as I can.
Sorry for nitpicking and not recommending download, probably I simply misunderstood your idea…
