That's a really neat concept. I would put the second level after the third level. It could use some other mechanics to add puzzle challenges, other than the red line. But really nice core idea.
Yeah the laser took some time to implement as I was not that much familiar with raycasting, so that didnt leave me time to add in other mechanisms..and yes, some people did find the 2nd one harder + I didnt like what i did with the third level so I'll change it and make the game longer after the jam. Really liked making this one.
Anyways, thank you for playing !
