Thank you for the continued feedback! I love hearing it! :D
So, currently floors have multiple exits, this is intentional! I will be changing this in a future version, however.
The crash you experienced I'm 99% sure has been fixed in the upcoming Friday update; I was having some trouble with enemy AI getting stuck in an infinite loop, but not anymore.
Lastly, seeded random generation is only partially supported in this version, so even with the seed it may be difficult to reproduce a bug. However, that is a tremendous idea to make the seed visible for future reference, so I'll be adding that in the next version! Hopefully once I find a good RNG library to use, the seed will be useful for reproducing issues.
