Thank you for playing my game!!
So the first bug we think is because of Unity Physics on Web platform because we could not replicate it on the desktop build
The second one is less of a bug and more of a design flaw. So basically it is two separate level and you are placed on two different side of the wall. In the first one you are supposed to figure out that you can swing and release to get the key. In the second one you have to figure out that you can go on the left side of the wall and solve the puzzle similar to the first level. If we had a transition between the levels then it might have been better but again... time constraints...
