Thx for the feedback, I am glad you enjoy it.
On the control bindings I understand your point and readjust the key binding on the rotate function on the R key and move the restart to the Tab key hopefully this will help prevent anyone else from accidently pressing restart again.
On the point of destroying the buildable items and you won't get it back that is actually intentional the idea I was going at the beginning was to have some sort of resource management also include in the puzzle where in later stages possibility there could be ways to collect extra buildable item to help further navigate around the map. Because in this game you can kind of just let the character play and build at the same time therefore I didn't intend for the player to be able to destroy and gain back the item as it may make the puzzle too easy if let say I give them too much blocks and they can just recycle the blocks as they goes through the level. But in the future I would consider coding it to make it able to destroy and regain back the item within that specific build window.
