It even has daily trivia and a currency -- necrocoins.
I think it went relatively well, but I can understand why other people go for serverless solutions.
For those that want to know, google cloud's free tier was and is enough to handle a bot with relatively low amount of active players (around 590 as of this post)
I like the serverless approach because if the bot commands are only used a few times a day, the lambda only has to run a few times a day and takes at most 0.5 sec (Discord has a 3 second timeout for slash commands)
BTW, Fusebot is not subject to the 3s limitation. We take care of responding to Discord within 3s and then let you run your code for longer than 3s and send any number of responses afterwards.
I haven't really considered open sourcing it yet, but I can see how other monster taming games may eventually want to implement something like it ;D
