Softlock in Photon Factory (not very severe imo)
Steam 1.0.4
To get the softlock, you backtrack after flipping the conveyor switch on the switch mechanic introduction room, instead of going to the right. You can go back up a few rooms with their conveyors reversed, but then you hit the softlock. If you make it back up (past the z shaped room), you'll get blocked off by a -1 count block (or whatever they're called). Trying to go back down past the z room again is now impossible since the conveyors down here have been switched to block your path.
Just wanna say that I started playing the game today and it has been really fun so far (I've done the first two levels + practiced the tinted versions, gonna come back for those later). Really nice level design and music :)
