I was really excited to try this out but I got caught in a loop on the ladder at the start. As soon as I reached the top it just spawned me to the bottom of the ladder again...
Yeah the game is "finished" but we had some bugs that we couldn't fix because we had a time limit but I'll be happy to fix this issue later. (ps : actually you can go up if you try to look up while climbing, it's just that a lot of times the character just falls like a brick on the ground)
