Hi, I started this as a prototype back in January using Vectrosity by Eric5h5, and have been working on it solidly since then as an iOS game. I’ve got 30 levels created so far and I’m currently working on the 2nd boss fight level. Here’s a preview trailer of what I have so far:
I’m aiming to have 60+ levels with 4 boss fights… so I guess I’m halfway there! 
Hoping to have it finished by April 1st 2013.
You can follow and maybe find some other info on my Cable Ride facebook page too.
Thanks for looking!
