Good start to what seems like a prototype of a mini-boss level in a much larger game. I like the cute blocky graphics and the parasitic alien theme, and the double jump flip is really sweet. I would love to play this game in an expanded metroid type of design.
The highest score I could attain was 23. I am wondering how the aliens chunk up into blocks that can be captured. Also, my character died jumping off of the screen, but not when jumping over an alien off the screen.
Nice mechanics, I would love to see more.
