I could totally understand New Game + mode on the added gravity, timer, added difficulty ... for applying pressure to push on each level, but really doubt or seriously believe anyone could complete the No Death Mode and really got the achievement through real effort. No Way 2% users completed that....

sorry for my bad English. How can I go through the last door?Even if I open the door once,I cannot go through. Because the door close before I reach and there are no other keys around. http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1311320666

Invisible wall, before and after hitting the button, and button doesn't disapear after pressing it. Pressing the button also hasn't removed the barrier to continue the level. (pink hitting invisible wall before button press) http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1347598038 (blue hitting invisible wall after button press, barrier still exists after button press) http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1347598120...

Or when would they appear?

I really like the music and I can't find out the artists name
