I've finshed my first version of the PRO levels run. Current time is 3m 29s. You can get it from the same URL as before,

I'm pretty happy with PRO levels A, B and C, though on level D, You'll see that I have to wait for several seconds to trap the two enemies. If I don't trap them, I don't think it's possible to beat that level, somehow I have to get them out of the way, and I don't have enough shots to shoot them. If someone has any idea how to solve this without having to wait like I do right now, let me know. Oh, and the reason I don't move when waiting on that room, is because if I move, I'll change the enemies movement, which I don't want, since I want them trapped. Anyway, If I could skip waiting on room PRO D, I could probably cut down the time to around 3:20. Though I don't think the other levels are that improvable.
All I really wanted to say was that feel free to comment this PRO level run, or this submission itself too for that matter. :)
