When you said this game was challenging you were not lying! Got to round 6, and had a lot of fun doing it. It is interesting how my playstyle had to change with the evolution of the levels, from lackadaisical orb collecting to focusing on dodging the 3209 bullets coming after me and THEN worrying about maybe getting an orb or two. My favourite level type was undoubtedly the one with the spinning thingy that shoots bullets in a circular pattern -- it was so hard! It would have been cool to have an ending screen where AMB1 and D3X-TR met though, every time I had time between stages I just put them as close together as possible to hang out </3
Also, the "combat" music is capital G Good, though sadly there were a couple moments where the sound volume fucked up and peaked and I had to turn it down.
Anyway, loved the used of both arrow key and WASD. A great use of the theme, which is always a plus. Great game overall :)
