Great game. I enjoyed it.
Sometimes it is not obvious what can be moved. I managed to move a light emitter in one of the levels.
Choice of escape for skipping levels is not great because it causes the game to exit full screen mode in browser.
Thanks for playing! Communicating clearly what is movable was a concern we had, originally everything was movable, but plans shifted as we made the levels. I’ll also patch it to change the skip level button. Thank you for the feedback!
