This is the same as the request here:
viewtopic.php?p=61331#p61331

The Lua library is custom compiled with the blocks xor'd with the key 'snailgame'.

I don't use QuickBMS, so I can't assist with that.

Due to the number of people that have contacted me about this game/encryption, I have made a tool to do this. However, I will not be sharing said tool as I know it will just land up being resold or abused for sale elsewhere due to some forums already reselling other files for this game.

You can contact me via pm in regards to decrypting files for a fee.
You can also contact me via Discord: atom0s#0001

Came across this, any XOR-related obfuscators. I have created a working tool to strip the wrapper function and successfully decompiled it.

Added, for anyone else interested, I am still offering a small fee service for decrypting this game's files.
I just rewrote/updated my tool as well for this.
