Shoot sound like a bug. I'll look into fixing it (can't alter the jam submission at this point obviously though). If your guards were loaded into the first room, not making them play the death animation can make the player get stuck in a similar way.
Hey Ash, it means a lot that you played it! And yeah I'm still getting used to how unreal engine renders and computes visuals and blueprint scripts and stuff. Performance & file size are crazy in this software for sure...
Thanks for checkin this out! That's just encouraging you to go up higher :) Do what ya want, but I find it more interesting to take a less direct path up the city. And there are some weird little things hidden around too if you go poking your nose around.
