Cute demo, I like the idea behind it. My only problems:
- the slow movement of the player actions/movement - it make me just hold the button and wait for a long time
- climbing needs W and R, I think it should be directly happen when you walk toward the area to climb without W since you can't push objects around. If you can push objects around then it make sense in its current form.
Thanks a lot for supporting HTML version of the game :)
