Thank you! The black screen is an HMTL5 only issue, since we didn't have time to really iron out all the kinks of that version. We've since decided to take that version down so it's only the Windows edition, if you want to give that a shot, but no pressure!
Otherwise, I'm glad you liked it, and I'll keep the death thing in mind-- you're probably right that we could have added checkpoints of something. Thank you for the feedback!
