The achievement says clear floor 1 through 100 solo. And I've done that but I didn't get the achievement to pop, I did die once on 91-100, is that keeping it from activating? If so that is a little aggravating. Understandable, but a tad upsetting since it doesn't explicitly state you have to do it without dying. Would be nice to have that confirmed or denied or if I'm just experiencing some weird bug?
Cause it still gave me a score screen along with 'new high score' when I cleared floor 100.
