I feel like this would be much better if all the bosses were made warp immune. The only two alien bosses took the top 2 positions, and a significant reason for that (especially in Wan Wan's case) was the fact that Warp is a downright broken ability when used against bosses.
I can tell what stages they are and everything easy but I cant understand your language or what any of it says. I do gotta say i like the video very interesting and fun to watch (i stumbled across this and on my xbox im watching a 3rd video made by you)
