@MScript Spoiler: hint did you notice the stairs in highest floor? this stairs have influence on the lowest floor so that B cannot trespass and follow that magic route.
Completed. A very surprising and innovative application of a bug that I may have not yet seen. I also do not yet understand how you achieved the effect. Perhaps you'd like to include a link to this level in this forum thread. The design is definitely well crafted as it is both challenging and artistically balanced. My only complaint is that the slider is not on a rail or otherwise blocked from having a bot step onto it. A slider in a vertical orientation can trap a bot from further movement. The addition of a bit of water perhaps just to half a block height may also make the level a bit more attractive. Thanks for sharing something both cool and worth playing!
@nGord Thanks for your advice. Spoiler: about the effect there exist some stairs above(highest floor).If you played the other level I posted the same day,you will find out easyer.
@Mike_CN sorry, you're right. I always seem to mix up R and B... Thanks for the explanaition! Hadn't seen this yet!
