Thank you!
Unfortunately, I don't know of a solution to the level 2 camera glitch (other than going down the ladder briefly and back up). For some reason, it seems to not carry through on the move-camera event. You'll notice that when this happens, the bottom half of the construction sign on the left disappears. This is a part of the script meant to hide it from covering up the HUD once the camera is in place.
Since the move-camera event doesn't always register, I added an additional copy of the event in the script AFTER the construction-sign-hide event and that won't be registered either when the glitch happens.
I don't believe any other actors are interacting with the camera controller actor so I don't know why this happens sometimes.
For the player sprite, I wanted to emphasize the size of his frame to give the impression of him being larger and (most importantly to the control) more heavy. I've tried different styles but this size of arm in combination with the smile fit the best in terms of representing the character visually and conveying a sense of a large heavy character to be fitting to the feel of the controls.
