1) Health did not regenerate. This was mainly a problem in that falling into lava gave you a second to get out and live, but due to no health regeneration required you to have full health. This led to the best situation if you lost health to be try to find a checkpoint, then suicide.
2) Checkpoint did not function. Small gripe here, the checkpoint before the elevator hatch/overcharged instant kill level has a checkpoint. Dying after using it listed "your bed is obstructed or missing" and used the normal level spawn (IE the entire beginning). Only checkpoint I had this problem with.
Also, I noticed the game 'ended' after 4 levels, but using creative mode and flying around I found what looked to be a almost entirely functioning 5th level labeled as the 4th (zombie fortress explody one), a 5th one with nothing yet in it, and a giant arena meant to fill with lava. Somewhat neat, but wondering what happened since the exploding fortress one sounds like something implemented but I could not find a legitimate way inside to begin the world.
The Zombie fortress escape level is based on a Metroid Prime level and was removed like 3 years ago due to bugs. If you look closely you will see where I blocked off the tunnel and redirected the game. The map was ahead of its time in 2013 and people did not understand that there was a countdown and how to get out, maybe now it would be more successful. Like, when this map was made, it had chat messages, clickable signs and countdowns before there were even command blocks or scoreboards...
excuse me, could I get a alternitive link to the 1.11 version of this map? I could not download the map because the website its on detected that I have a ad blocker on and it would not let me continue unless I disable the blocker (The blocker is a kind I can't easily disable)
