My 1 hour run ended due to a mess of large plates and activated magnets getting stuck in the tube, and due to how high it was I could not unjam it before the height check respawned me. Definitely need to fix that for full release.
Huh, I would have thought the fix would be to make plates not get stuck in place unless released by the player. Good to see the game is improving, will wait for Steam demo and definitely buy the full game.
