Great concept lot's of fun. Awesome idea for sharing with a community during a game jam, nice and simple copying the clipboard data.
Although I had some bugs I think? If I died to a slug on a level you made it takes me to an empty editor with the same heat level and name as the one I was playing. Shooting anything on the L shaped blocks is impossible because it only detects that game object first, so you can't shoot anything sitting on that block until it's destroyed first.
Otherwise great work, something different.
