Wow, it's so good but it's sooo hard! I managed to get the first one by hiding behind an asteroid the whole time. I could touch it, but it couldn't touch me xD
The second one seemed easier to dodge, but since I died I didn't want to do the first one again, sorry x)
But it's really cool, well done!
Edit: Wait, there's the right-click dodge, I'll do it again!
