I'm only up to the second level and I'm stuck.
Can I move pieces or delete them after they're dropped?
Why can't I stand on placed objects after I climb them?
How do I save my progress?
Also, the game seems buggy. Whenever you reset a level, it remains paused and you have to press Return to start. One time the countdown stopped and the retry didn't work properly, Plus, the pen covers the first item and the pieces don't display correctly in thumbnail. (Not sure how much of this is because of my old PC)
