I have been trying this level for a while but I cannot get past the last bubble, no matter what polarity I use, it just pops and drops me into my death. Is it broken or what am I doing wrong?

Game opens, splash screens play out, but then perma black screen with nothing happening. Probably not a common problem, but I can't even begin to play the demo.

Question about the no death achievements: what exactly do you have to do? Do you have to go through all of the levels at once without dying, or can you just do them one at a time? What needs to be done for these achievements is not very clear to me at this moment. Also, what is the criteria for the 'fast' achievements? Any input would be greatly appreciated....

Seriously! It reminds me of how music sounded on the Genesis/Mega-Drive. In particular, I'm reminded of Phantasy Star 2. Great work!
