Very nice. The music is a bit too repetitive as mentioned already. After playing through I just got a black screen without being able to continue.
On a second play-through I noticed I can pretty much just "run through" - I can evade enemies or run away. But I still got only a black screen at the end. I'm playing on Linux using Wine so that could be the problem.
Kudos for using Blitz and not Unity :D and the extremely small file size!
