These levels show strong technical proficiency — you know how to use bridges, trigger crates, destruct/stomp blocks, animations, swinging platform, layer properties, and so on — but little else. The first level (I managed to guess the level order based on your plot description, but in general it is better to indicate clearly in the filenames which level people are supposed to start on) presents no challenge at all because all the enemies can be jumped or coptered over, and the same goes for the second level up to the boss, which is totally uninteresting. We’ve all fought all the bosses in empty arenas before — to make them interesting, at the very least there should be some interesting eyecandy around them, and better off there should be something to make the fight different than usual. I think it was Shellion’s Xtreme Revenge, for instance, that had you shoot through a number of destruct blocks while avoiding the Tuf boss’s flamerang. Not hard to make in JCS, and not itself the most interesting boss, but still better than this. Basically, you need to spend a lot more time thinking about your levels. You obviously know what you’re doing in JCS so far as using events goes, but the execution falls flat if there’s nothing new in the level design for people to be interested by. Also, perhaps as a secondary concern, spend more time on your eyecandy. You’ve got layer 8 down, but the other layers are pretty rudimentary so far, and could be a lot prettier. As long as you’re sticking to the official tilesets, even looking at the official levels should give you ideas for how to make yours more appealing to look at, although eventually you may want to start handling things more creatively there too. Keep at it, and be thoughtful.
