I'm starting to sound like a broken record but I've never been the biggest fan of platformers. It was still fun to swing around though, and navigating the levels felt satisfying. I guess no matter the game I always like a good grappling hook of some sort.
The only major issues I have are that the game never tells you that all viruses need to be killed before exiting the level (like everyone else mentioned and you'll probably have fixed in the next update), and that sometimes it seemed like I was getting killed even though I was landing on enemies from the top or at least the top half of the side. Maybe its just me but I would've expected a game where you're whipping around from all angles to be a bit more forgiving on this front. Like I said though I'm no platformer expert so maybe that's just how things are.
Overall though, not bad, only made it to the third level but I enjoyed what I played. Nice work!
